Return amplifier identifier from header as string.

get_filter(hdr)[source]

Return filter name from header; leading segment before underscore.

get_number(hdr)[source]
get_time(hdr)[source]

Return MJD from header (mjd_keyword) as float.

import_image(filename, amp, log=None)[source]

Parameters:

  • filename (str) – Path to raw FITS file.

  • amp (str) – Amplifier identifier (number of extensions).

  • log (ColoredLogger, optional) – Logger for progress.

Returns:

Processed frame in electrons (single combined image).

Return type:
