[daip] Bad handling of multiple spacecraft?

[Walter Brisken]

In our recent salvo of spacecraft tracking tests, two different spacecraft 
were observed in the same observation, yielding FITS files containing 
spacecraft orbit tables containing two spacecraft.  In the particular 
case, the table entries for the two spacecraft have identical time tags 
(not sure if this is relevant to the problem or not).  In AIPS, only 1 of 
the spacecraft appears in the table.  PRTAB does not indicate which 
spacecraft it is, but it is clear from the X,Y,Z values that only one 
spacecraft is present.  There is concern that some of the subtle 
corrections made by UVFIX, CLCOR, or other??? programs may not be doing 
the right thing as a result.  We are not exactly sure which AIPS tasks 
access the table.

A FITS file is available : /home/swc/difx/projects/ts022b/TS022B.FITS

Please keep Vivek and Ed in the responses to this.  Thanks,
