Region selection in cgdisp
Posted: Wed Jun 19, 2019 5:38 pm
Hi again,
Quick question, more of a confirmation. I'm zooming in to my region of interest in cgdisp using the box method, I'm looking at a protoplanetary disk so it's very small. The region documentation on miriad says for the arcsec option "the coordinates are in arcseconds, relative to the reference pixel". Does this mean that my region (where the size is defined by my box input) will be centred on the reference pixel, where this reference pixel is (in RA and DEC) what I pointed the telescope at during the observations?
Cheers,
