In an attempt to reduce the amount of time needed for proofing, it would be helpful if contributors could adopt the following conventions:
| Preferred Format | Comments |
|---|---|
| General: | |
| Normal typing style except only use one space after full-stops. | Except for headings, never type anything in ALL CAPITALS – it is difficult to read. With computer publishing, double-spacing after full-stops is unnecessary. |
| Dates: | |
| 20th August, 1999 On 20th August 1999, we observed... Saturday, 20th February Thursday, 18th March |
Full month rather than Mar., Apr., is easier to read. With or without comma before year. Include comma after day. Lower case in superscript is nicer. |
| Times: | |
| 4:30pm 6am |
Full-stops and spaces can cause problems, as the numerals can become separated from the letters if occurring at the end of a line. |
| Spelling: | |
| kilometres colour program |
Generally adopt the “English” style rather than the “American”.. … although “program” has now crept into common use, and is easier for you to type (as opposed to “programme”). |
| Page Notations: | |
| April Universe, p7 Astronomy Magazine (pp38 – 62) |
Again, no full-stops, commas or spaces between the “p” and the numerals. “pp” is the plural. |
If using abbreviations for catalogues, NASA acronyms or anything that is not generally well-known, the custom is to write it in full the first time you refer to it, with the abbreviation in brackets immediately following. From there on in your article you can just use the abbreviation. If ever in doubt about the correct format for an abbreviation, use the complete word – it is easier to read anyway. Likewise for Greek letters in star names, (e.g. Alpha Centauri.) you don’t have to use the Greek symbol.
| Abbreviations: | |
| mag | e.g. “The star appeared to be 6th mag, although the catalogue states mag 6.3.” or “the stars were of mags 6.2 and 3.1”. |
| mags | |
| The abbreviations should only be used if making frequent references. For solitary references, write magnitude or magnitudes. | |
| etc. | Include full-stop |
| BC | Omit full-stops |
| AD | Omit full-stops |
| scopes, ’scopes | With or without the leading apostrophe. The apostrophe is tricky, as the computer will make it go the other way. You need to type it after the previous word, type scopes and then go back and put the space in (do this for years as well, like ’99) |
| M67 | Messier numbers, no space between the “M” and the numbers |
| NGC 5460 | NGC numbers do have the space |
| IC 4402 | and so do IC numbers |
| i.e. | This is tricky because your computer will probably try to capitalize the i for you. After typing the “.e.” you should be able to go back and amend the “i” and it will stay in lower case. |
| e.g. | Include full-stops |
| R.A. | Capitals, and include full-stops |
| Dec. | Capitalised, and include full-stop |
| SSE, NW | Capitals, and omit full-stops for multiple cardinal directions |
| north-west | Hyphenate if writtin in full |
| 7°S | No space or full-stop, or else |
| 7° south | Leave space and lower case if direction is given as full word |
| arcsec. / arcsecs. | One “word”, include full-stop |
| arcmin. arcmins. | Likewise |
| m.arcsec. / m.arcsecs. | Milliarcsecond / s, or can use mas if it is obvious what you mean |
| max. | maximum (include full-stop) |
| min. | minimum (include full-stop) |
| Telescopes: | |
| 50cm | Omit space and full-stop |
| 18-inch, | 18” Use hyphen for word |
| f/7 | Slash between the “f” and the number |
| Dobsonian, Newtonian | Capitals – named after people |
| reflector | Lower case (not a person) |
| refractor | Likewise |
| 100x | (Means 100 times magnification) Lower case x, no space |
| Eyepieces / Filters: | |
| 12mm | Omit space and full-stop |
| O-III | Not O3 or O111 (the “III” is a Roman numeral) |
| Physics Terminology: | |
| newton /N amperes / A hertz / Hz | Even though named after people, when using whole word as a physics term, use lower case, but if using abbreviation, use upper case and no punctuation e.g. It was a 6N force. |
| Distances / Speeds: | |
| 8.75 l.y. | light year (include full-stops), same if plural |
| 120pc | parsec (no full-stop), same if plural |
| 60kpc | kiloparsec, kiloparsecs |
| 10Mpc | Megaparsec, Megaparsecs |
| 40AU | astronomical unit (capitals, omit full-stops), same if plural |
| 120km | omit spaces as often the numbers get separated from the abbreviations when they fall at the end of a line |
| 18km.sec-1, 23kms-1, 42km/s | These are all correct, but please choose one format and stick with it throughout the whole article. |
| Degrees and Large Numbers: | |
| 5,800°C 7,000K 45.23509 | Please use commas for thousands. I don’t know why on Earth they’ve got rid of them recently. They make numbers much more readable, and if you leave spaces you will end up with your “7” on one line and your “000” on the next. No commas after a decimal point. Celsius temperatures are measured in degrees. Absolute temperatures are measured in Kelvins (omitting the ° degree symbol). |
| Grammar: | |
| with respect to | e.g. “Enquiries with respect to the details…” |
| compare with | This is the correct form in most cases. It means “to note the similarities or differences of”, e.g. “When you compare this with its appearance twelve months ago…” |
| compare to | Rarely used, means “to liken to”, e.g. “Shall I compare thee to a summer rose ?” |
| respectively | Only use this if there have already been two or more items referred to in your text. e.g. “The primary and the secondary have 5.3 and 2.4 solar masses respectively.” Otherwise, just say “the two stars have 5.3 and 2.4 solar masses”. |
| its | This is possessive, e.g. “its colour was breathtaking”. |
| it’s | This is short for “it is”, e.g. “I think it’s going to rain”. |
| Punctuation: | |
| Colon : | Used if you are about to say something. Do not use a dash :- unless you really intend to draw a sideways smiley face. |
| Semi-colon ; | Divides ideas in a list which appears after a colon. |
| Hyphen | A short dash used for two-word terms (no spaces) and particularly for compound adjectives made with two regular words, e.g. "the naked-eye view" |
| Dash – | Leave a space before and after a dash – used to separate ideas. |
| Quotations and Brackets: | |
| If an entire sentence appears inside quotes or brackets, it should begin with a capital letter and end with a full-stop, also inside the quotes or brackets. e.g. (The reader may refer to previous articles.)
If a bracketed remark is a full sentence, don’t try to include it inside another sentence, but have it appear at the end, e.g. Nearly 2000 signed. (Try to beat that today!) If the quote or bracketed remark falls within, or at the end of an existing sentence, then close the quotes or brackets before the full-stop or other punctuation. e.g. These stars are known as “the pointers”, and are easy to find. He said “please show me that star”. The orbit is obviously elliptical (see Figure 1).
Other conventions still apply inside the brackets, e.g. The distance is given as 2.683 parsecs (8.75l.y.). |
| Unusual Plurals: | |
| spectra | more than one spectrum |
| radii | more than one radius |
| axes | more than one axis |
| maxima | more than one maximum |
| minima | more than one minimum |
| nebulae | more than one nebula |
| aurorae | more than one aurora |
| phenomena | more than one phenomenon |
| Capitalization: | |
| Earth | Primary Solar System bodies and common names use capitals. |
| Sun | Use lower case for moons if they are moons other than our Moon. |
| Moon | |
| Milky Way | In the case of star names, in mid-sentence, you can use lower case for the Greek letter as in alpha Centauri, though if submitted in upper case, it will be left that way. |
| Finishing Off: |
| DO use tools at your disposal – spell-check and grammar-check may give you lots of irritating things which you want left the way they are, but they will almost certainly find some errors you’ve missed. A regular dictionary is also handy.
TRY proofing on paper, as well as on the screen – punctuation, in particular, is difficult to see on the monitor, but shows up easily on a print-out. You will also think of better ways to word things if you pick it up and read it some time later. Even try reading your article out loud. DON’T PRESUME KNOWLEDGE. Many readers are new to this business, and may not understand abbreviations that you take for granted everyone knows. If in doubt, write in long form, or include a key at the end of your article. And remember that not everyone will automatically know that Delta Corvi will be found in the constellation of Corvus.
DO feel free to submit your constructive ideas, criticisms, or pet hates to the Editor for inclusion in future updates of this guide. |
