To accompany the data, we request a document in ASCII which follows the format
used by the Centre de Données astronomique de Strasbourg (CDS). Not only does
preparing the document in this form make interchanges between the two data
centers easier, but CDS has written a substantial amount of software which
permits easy checking of the catalogs and automatic conversion to FITS format.
Although the description appears lengthy, we find it rather easy to follow.
The CDS standard is described in CDS Bulletin #44, January, 1994, p19. An
updated draft version is available via anonymous FTP at
adc.astro.umd.edu/pub/adc/docs/. A template for the document
with modifications covering the ADC needs is as follows:

Description: [required]
This describes the data in the catalog in general terms. [required]
It should allow the astronomer decide whether the data are [required]
useful for his/her purpose. In general the type of data [required]
and any pertinent details should be mentioned. Normally, [required]
it is not the abstract of the paper as it should not [required]
discuss results. [required]

Each section header is left flush, starts with a capital letter and ends with a colon (:). The main text of the section is indented except for the long title and byte-by-byte descriptions. The indented text should have lines no longer than 72 characters. In the File Summary heading "Filename" must be indented at least one space.
There are standard lists for the "ADC_Keywords" , and the "Mission_Name" , and for some of the labels (see label.txt and lprefix.txt), units (SI) and symbols (see unitsym.txt and msubmsym.txt ) in the "Byte-by-byte Description". Also note the standardization of the section header names:
ADC_Keywords: Description: File Summary: Objects: See also: Nomenclature Notes: Byte-by-byte Description of file: Note: Remarks: Acknowledgments: References: (END)
where the capitalization and spacing and ending colon are important for automatic recognition.
The Byte-by-byte Description is required for each tabular data file; it is not required for plain text files without tabular structure.
The optional text sections describing the catalog should interleave the required sections in a natural way. In particular the Byte-by-byte Description table should be close to the text describing the same data and not in a group at the beginning or the end of the document.
The following is an example of a "ReadMe" file. However each catalog has its own needs. We are interested primarily in your lengthy tables. Shorter ones should not be included unless they are essential to understanding the catalog or major tables.
II/177 Near IR Photometry of a Sample of IRAS Point Sources (Fouque+ 1992)
================================================================================
Near Infrared Photometry of a Sample of IRAS Point Sources
Fouque P., Le Bertre T., Epchtein N., Guglielmo F., Kerschbaum F.
<Astron. Astrophys. Suppl. Ser. 93, 151 (1992)>
=1992A&AS...93..151F
================================================================================
ADC_Keywords: Mass loss; Photometry, classification; Stars, carbon
Description:
The results are given for the 516 sources that were observed from
La Silla (452 in the southern hemisphere, plus 64 in the range 0 to
20deg). For each source, the IRAS name is given followed by the epoch
of observation (with the convention given in note on epoch), the
J, H, K, L', M magnitudes that were obtained, then three classifications
based on IRAS Low Resolution Spectra (LRS), IRAS broad-band photometry
(VH) and the combination of IRAS broad-band photometry with the
near-infrared photometry (Val), and, finally, one association.
