Calibration tool: check_calib
=============================

check_calib - DEPRECATED tool that checks a calibratation at the
sub-pixel level

Purpose
-------

usage: check_calib [options] **-p** param.poni image.edf

Check_calib is a deprecated tool aiming at validating both the geometric
calibration and everything else like flat-field correction, distortion
correction, at a sub-pixel level.

Note that \`check_calib\` program is
obsolete as the same functionality is available from within pyFAI-calib,
using the \`validate\`, `validate2` and
`chiplot` commands in the refinement process.
