Write IMAGE to FITS file filename.
Datacubes will be saved as multi-image extensions.
The optional parameter bit_per_pixel specifies the data type of the pixel values. Accepted string values are BYTE_IMG, SHORT_IMG, LONG_IMG, LONGLONG_IMG, FLOAT_IMG, and DOUBLE_IMG (default). Alternatively, corresponding numbers may be passed, i.e. 8, 16, 32, 64, -32, and -64.
Use a preceding exclamation mark (!) in the filename to overwirte an existing file.
Lossless file compression can be used by adding the suffix ’.gz’ to the filename.
