[daip] Spectrum of a blotch region

[Gary A. Welch]

Dear Aips Helper,

1. I wish to plot the summed flux within the B=25 mag/square arcsec optical 
contour of a galaxy vs velocity.  I can display the contour using TVLOD and 
TVSTAR. 

I guess I need to use BLSUM.  In that case, though, I'd like to display the 
contour as a guide in defining the blotch region.  I can't figure out how to do 
that.  Can you help?

Regards,

Gary Welch
