python wht_basic_reductions.py [full_path_to_raw_data] [full_path_to_reduced_data]

Create wave maps for each of the arc frames

python wht_measure_arc.py [arc file]

Apply the wavemaps to object frames

python wht_calibrate_objects.py [full_path_to_reduced_data]

Rectify all the images in the current directory
