******************************** Image Calibration Implementation ******************************** The :doc:`low_level_image_calibration` provides tools to: * manually calibrate frames. * stack calibrated master, bias or dark frames into masters. The :doc:`low_level_master_stack` provides tools to stack a collection of calibrated bias/dark/flat frames into a master. Designing and implementing the higher lever interface is still pending. The high level interface must: * automate the process * take its configuration and log progress and results to the database * provide crash recovery
