Each one can be turned into a separate MIDAS table file, as just described; then, if you wish, the tables can be combined into one big table, using the MERGE/TABLE command. Note that the column display formats will be taken from the <I>first</I> of the merged tables; this may influence the order in which you do the merging. <P> If the formats are different, you may want to keep the program-star tables separate. In any case, you should keep standard, constant, and variable stars in separate tables. Then you just enter the names of the different tables one by one, as you run the planning and reduction programs. <P> A more convenient way to handle multiple files is to make a catalog, and then just supply the catalog name. Only stars of a single type (standard, constant, or variable) should be kept in the same catalog. At present, only the reduction program can use star catalogs. <P> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
