Note of guides to manuscript preparation to AAS

Terms defined in the abstract should be defined independently in the main text.

$km s^{-1}$ rather than $km/s$.

dates are written in the order: year, month, and day (e.g. 1996 January 1). In tables, use three-letter abbreviations for months, without a period.

avoid beginning sentences with a symbol, number, or lower-case letter.

in a series of three or more items, include a comma before the final item (e.g., "space, time, and matter")

including line numbers in your manuscript provides an easy way for reviewers  to reference specific locations in the text thus we encourage authors to include then in both submission and revision. (\usepackage{lineno} \linenumbers)

first level titles and appendix titles should all be in capital letters; the title of second level should capitalized on the first letter of each word, except for articles, conjunctions, and prepositions.

footnotes should be confined to providing URLs, affiliations, or other peripheral information, and should not be used for discussions of, or expansions on, the text.

For convenience of citation of equations, authors should number all displayed equations. Equations should not be referred to by their number alone. "substituting equation (45)" rather than "substituting (45)."

vectors are normally distinguished by bold italic type; arrows over symbols are not used to denote vector. vector operations and operator are also set bold.

tensors may be set bold non-italic if it is necessary to distinguish them from vectors.

values given in scientific notation should be expressed with a multiplication sign preceding the power of 10 (e.g. $3.4x10^-2$); in table only, the form 3.4E-2 may be used.

single-letter subscripts and indexed referring to variables are conventionally set in italic.

stacked fractions are not permitted in the body of the text or in superscripts.

all tables are typeset with horizontal rules only; no vertical rules are used. column headings should label the entries concisely, the first letter of each word is capitalized. units of measurement should be given in parentheses immediately below the column heading. to indicate the omission of an entry, ellipsis dots are used.

Figure legends should distinguish (a),(b),(c), etc., components of the figure. All lines and symbols should be explained in the legend.



How to write a scientific paper

 abstract

1-2 sentences on context and aims (why/ context & aim)

short description of what has been done (how/ method)

main results and major consequences (what/ result & conclusion)

Example:



---------------------

introduction

1. describe the background and context of the work, i.e., what has been done before. Give enough credit to the work of others.

2. why the present work need to be done. why it is important.

3. what is new in the method or results.

-----------------------

Methods


-------------------------

Results

General rule 

1. in the results section, you only describe the results, but do not interpret them very much

2. in the discussion section provide the interpretation and the comparison with the literature, without repeating all the results.

3. use figures to show the main results if possible

a) captions should be short, but self-explaining. since often figures are looked at before the text is read. if symbols or abbreviations are used, then they mush have been defined in an earlier figure caption.

b) captions should only clarify what is plotted and not try to interpret the figure. interpret the figures in the main text.

c) should give all the information needed to understand the figure.

table

must have a title

describe the different columns of the table. i.e. as footnote to table or main text.


-------------------

discussion/conclusions

discuss, compare with previous work and put into perspective.

limitations, potential sources of error, and possible improvements are also discussed here.

List your conclusions at the end.

it may be appropriate to repeat the MAIN results, but definitely not all of them


Reference

if you are using unpublished data or results of another researcher, then cite him/her in the text as, e.g., "M. Monroe (private communication)".

No private communications or un-submitted papers into the reference list.

papers that have been submitted, but not yet accepted for publication are cited as "submitted", those that have been accepted as "in press".

------------------------

Appendices

material that may be of interest for a few readers, but not for most (e.g., lengthy tables, derivations of equations) can be put into an appendix or into multiple appendices.

An appendix must be referred to in the main paper. e.g. " The derivation of Eq. (15) is given in Appendix B."

--------------------------

You can't properly explain things to your readers unless you have properly understand them yourself.

An additional hour spent with improving and clarifying your explanations and arguments may well save you many hours revising your paper after a negative reference report.

----------------------------

shows, display, exhibits, illustrates, highlights, reveals, uncovers, can be seen from Fig., can be deduced from Fig., in Fig., we plot, sketch, draw,  Fig. is a plot pf, ... is a sketch of ...

---------------------------

impact factor: how often articles in the journal are cited on average in the first 2 years after publication

---------------------------

posters

Title (BIG) + authors +affiliation

abstract

a very short methods and materials section

main results

conclusion (short)

few references (no references is o.k.)
