[daip] Regarding some help in AIPS tasks {External}

[Soumen Bera]

Dear Sir,

My name is Soumen Bera, a student of Jadavpur University, Kolkata, India. Sir, I have the following queries.
(i) I would like to know if the LoTSS DR1 image can be overlaid on the PanSTARRS-1 Image through the task 'kntr' in AIPS. I have already done the overlay of radio image on optical image e.g., VLA FIRST or NVSS or TGSS or LoTSS DR1 (radio image taken from their respective radio cutout site) on SDSS or DSS (image is taken from 'skyview' site) using the tasks 'hgeom' and 'kntr'. But for PanSTARRS-1 the 'hgeom' and 'kntr', is not happening.

(ii) Is it possible to change the background image colour (optical image), such a way the background optical sources will be visible? We have tried 'ofmfile 'rainbow'' task, but as it turns the whole plot into a colour plot and the contour line in black, it's not easy to trace the contour lines.

(iii) Is it possible to draw the contour lines in different colours other than black?

Kindly help in this regard.
