need to make photwrapper able to handle off center objects #101

Closed rfinn closed 11 months ago

rfinn commented 11 months ago

Description

right now, photwrapper.py assumes that the object is at the center of the image, but sometimes the galaxies are offcenter if the object is near the edge of the halpha/r-band image.

Suggested Handling

add optional arguments of RA and DEC, with default values of None
if RA and DEC are not None:
- use the image header to convert RA and DEC to xpixel,ypixel
update the find_central_object to match by RA,DEC coords if they are given
I have already implemented something similar in maskwrapper.py, so check there.

this is fixed, pretty sure...
