ra/dec in degree in cursor WCS value

[eriniocentric]

Maybe I've missed it, but I don't think it's built into core.py. Can we have an option to switch the printed coordinate system info from hour angles to degrees. Thanks!

@eriniocentric , can you please clarify which core.py you are referring to? And please provide a minimal working code snippet to reproduce your example. Also, please state your Python, Numpy, Astropy, and OS versions. Thank you.

[pllim]

Oh, ops... I didn't realize this is not the astropy repo. Har har har. Nvm...

[pllim]

I am guessing you are using the Ginga backend? Are you using a released version of astrowidget or the dev version?

[eriniocentric]

Hi! I'm probably using the released version. Just the one that automatically pip installed.

[pllim]

But regardless, yes, I don't think it is possible for user to customize the display format without tinkering with the code. What you can do for now is to subclass the widget and then overwrite this:

astrowidgets/astrowidgets/core.py

Lines 211 to 214 in 2128835

	if image.wcs.wcs is not None:
	ra, dec = image.pixtoradec(data_x, data_y)
	val += ' (RA: {}, DEC: {})'.format(
	raDegToString(ra), decDegToString(dec))

Great.. that's what I was wondering..

Although I'm not quite sure how to subclass that through the ImageWidget I have. I'll try to dig a bit deeper. How do you call image = viewer.get_image() ? I see a _viewer attribute but it doesn't have a wcs attribute.

[pllim]

It is a callback method used internally, so it will automagically find the WCS if your image has a valid WCS. When you subclass, you can redefine that method basically by copy-pasting and only modifying the string formatting portion. I hope this makes sense.
