mDiff
(in_image_1, in_image_2, out_image, template_header, debug_level=None, no_area=False, status_file=None)[source] [edit on github]¶ mDiff calculates a simple difference between a single pair of overlapping images. This is meant for use on reprojected images where the pixels already line up exactly. mDiff analyzes an image metadata table to determine a list of overlapping images. Each image is compared with every other image to determine all overlapping image pairs. A pair of images are deemed to overlap if any pixel around the perimeter of one image falls within the boundary of the other image.
Parameters: in_image_1 : str
First input FITS file (Also needs area image in1_area_image, or use the no_area option)
in_image_2 : str
Second input FITS file.(Also needs area image in2_area_image, or use the no_area option)
out_image : str
Difference FITS image to be generated.
template_header : str
FITS header template used to generate output image.
debug_level : int, optional
Turns on debugging to the specified level (1-4).
no_area : bool, optional
No-area-images option. Creates difference image without requiring pixel area FITS image
status_file : str, optional
Output and errors are sent to status_file instead of to stdout
