| | ** In version 2 of PyWiFeS, the association of the pipeline steps with their particular file suffixes from the table below has been retained. But note that the final datacubes are renamed from p11.fits to cube.fits. In addition, regarding footnote C, standard stars are now identified by header keyword IMAGETYP='STANDARD' with a user option to also grab any IMAGETYP='OBJECT' exposures with sky positions close to the tabulated standard stars. ** |

| 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). | The default data reduction steps in 'reduce_red_data.py' and 'reduce_blue_data.py' are outlined below.
