aud is also designed to get data
out of the database for specific list of stars. The list may be prepared by
the user, or may be the numbers of stars belonging to a file of the database.If the list has been prepared by the user, the command
aud -f filename type
takes the list of star numbers in the file "filename" and looks for the data corresponding to the data type defined by "type". "filename" may also contain the access path to the file.
How to get a list of stars for which the data are absent is explained by the next item.
The file containing the star numbers should have one number per line, and the numbers should be of the form 0005 (left padded with 0).
aud -f star.lst mk displays the spectral types for the stars contained
in the file "star.lst"
