[daip] Help on AIPS {External}

[Soumen Bera]

Sir, I did not understand how to run the 'STARS'. Could you elaborate with
an example?

And about the overlaying issue of Pan-STARRS images, I have already tried
by using OHGEO or HGEOM. But it failed. It shows the maps are not
coincident either AXIS 1 or AXIS 2. However, HGREOM is unavailable. Kindly
refer to the attached images.

with regards,
