5.1  Description of Modules in the BCD Pipeline

Figure 5.2 shows the flowchart of the BCD pipeline, starting with the module CVTI2R4. The processing flow takes as input the file raw.fits, which was created from a MIPL (“Multi-Mission Image Processing Laboratory”) file produced at JPL. MIPL files contain a complete telemetry record of the observation. The file raw.fits is a MIPL file whose header has been processed by the module TRANHEAD to a more compact, more readable format.
