get (
        header,
        ideal=0,
        cache=1,
        )

Get calibration object suitable for a detector.

Look up all calibration data for the detector that was used to make the image of which header is the image header.

Parameters:

ideal

if ideal=1, get the idealized calibration data even if real calibration data are available.

cache

if cache=0, do not use the calibration cache to retrieve the data, and do not store the calibration data found in the calibration cache. This might be necessary if you want to change calibration data (temporarily or during calibration procedures). if cache=-1, stored results are erased from the cache first.
