Overplotting HST data - REDGRID?
Posted: Mon Nov 04, 2013 4:48 pm
Hi all,
I want to overplot an HST image and an ATCA image on the same figure.
I can't do this simply in kvis because the HST image has RA, Dec on a wonky angle, whereas the ATCA data are projected with RA on the horizontal axis.
Presumably this means I need to first regrid the HST data. Have tried for several hours with different settings but I can't work out how to straighten up the HST image so that RA is along the horizontal axis of the image.
Can anyone please advise me how to straighten up the sky??
Many thanks,
Lisa
