[daip] STARS

[Lorant Sjouwerman, NRAO]

In addition, after haveing read in the star file, and to avoid having to do 
that each time you want bigger/smaller symbols, many tasks like GREYS have 
an input parameter STFACTOR that controls the symbol size at execution of 
the task - type 'help stfactor' or 'explain greys' for more information

#15 arcsec.  The last two positions are plotted as normal crosses
#(type 0) and are 10 arcsec by 10 arcsec (columns 3 and 4).

#Sample file follows:

#  12 01 56.03  -18 53 22.2   15.  15. 0.  20  SN_1974E(J2000)
#  12 01 55.52  -18 52 47.2   15.  15. 0.  20  SN_1921E
#  12 01 52.82  -18 52 05.2   10.  10. 0.  0   N4038 Nucleus
#  12 01 53.62  -18 53 12.2   10.  10. 0.  0   N4039 Nucleus
