trim_objlist¶
- romanisim.image.trim_objlist(objlist, image)¶
Trim a Table of objects down to those falling near an image.
Objects must fall in a circle centered at the center of the image with radius 1.1 times the separation between the center and corner of the image.
In contrast to in_bounds, this doesn’t require the x and y coordinates of the sources, and just uses the ra/dec directly without needing to do the WCS transformation.
- Parameters:
- objlistastropy.table.Table including ra, dec columns
Table of objects
- imagegalsim.Image
image near which objects should fall.
- Returns:
- objlistastropy.table.Table
objlist trimmed to objects near image.
