(in_image, out_image, factor, fixed_size=False, debug_level=None, status_file=None)[source] [edit on github]¶ A utility for reducing the size of a FITS file, by averaging blocks of pixels.
Parameters: in_image : str
Input FITS file
out_image : str
Path to output FITS file.
factor : float
Size of blocks, in pixels, to average. File size will be reduced by 1/factor squared. If the fixed_size option is used, factor is the desired width of the output image.
fixed_size : bool, optional
Fixed-size option - specify output size of image, instead of the size of blocks of pixels to be averaged
debug_level : int, optional
Turns on debugging to the specified level (1-4).
status_file : str, optional
Output and errors are sent to status_file instead of to stdout
