Default Data Reduction Steps

The default data reduction steps in 'reduce_red_data.py' and 'reduce_blue_data.py' are outlined below. Most “steps” are numbered by the number of actual operations on data (e.g. step “1” ends when raw data goes through its first processing, and so on). Sub-steps consist of the calibration calculations performed after the conclusion of the previous step, and the final sub-step is always when a new processing of data occurs (e.g., step 3 consists of numerous calibration steps that occur after bias subtraction at the end of step 2, but before creation of multi-extension fits – MEF – files at the end of step 3).
