... Standard-star files, however, must also have the standard photometric values (in place of the rough MAG column). The column label should be the usual name of the magnitude or index in the column, e.g., V or U-B or c1; see Table . ... MIDAS table files do not distinguish between upper and lower case in column labels. Thus, while it is possible to use 'u-b' as a column label for the uvby system, it cannot be distinguished from 'U-B' by programs or MIDAS procedures that read these files. ...

SAOtng supports FITS files internally, so that a standard FITS image file can be sent directly to SAOtng for display using XPA: xpaset SAOtng Also, when a new file name is sent to SAOtng, the program checks the first 2880 bytes of the file to see if it is a FITS file and if so, processes it accordingly. Support for other image file formats (or any other image format) is added to SAOtng by writing two external file access programs: . ... The command-line of the image section program . ...
