[Soumen Bera]

Sir, I have to overlay the radio image (contour) on the optical image (gray
scale in the background). I have done that using the optical SDSS/DSS data.
But the problem is that in the final image, the optical host is not
properly visible. So, I need to mark the optical host position by a circle
or something else.

However, I am unable to produce the plot using the Pan-STARRS images as the
optical image. I have tried using the OHGEO or HGEOM, but it failed to do
so. If I use the Pan-STARRS instead of the SDSS or DSS, then the optical
host might have a better visibility.

I have attached an image with this email, where I would like to add a
circle at the optical centre (lets say at the centre of the sample image).

Kindly help in this regard.

with regards,
