Exposure Pipeline Steps And Data Products

The following table contains lists of all data product types for the Exposure pipeline, as given by their file name suffix. The input uncal file and the final cal file are the only files that are produced in the standard processing. All the other are optional (opt) files that can be produced when the user is running the pipeline. The input for each optional step is the output of the preceding step.

2-D calibrated data

The following table contain lists of all data product types for the Mosaic Processing Pipeline in the HLP, based on the step and the output file suffix. The input to the HLP is an association file (in JSON format), the outputs are a combined image, a source catalog of detected sources, and a segmentation map. All the other are optional (opt) files that can be produced when the user is running the pipeline. The input for each optional step is the output of the preceding step.
