Tables should be prepared using the table environment, following the examples given below.
Tables should be self-explanatory. The table headings should contain the essential information needed to understand the data presented. Details should not clutter the header and are better presented as explanatory footnotes. Large tables containing primary data can be archived at the CDS. For details about archival at the CDS, please refer to section Publishing data at the CDS
Table columns should be set flush left. Vertical lines are normally not necessary and should be inserted only in exceptional cases for the sake of clarity. The height of each table, including the caption, usually must not exceed 23.5 cm, and the caption should always be placed above the table.
