5.1.12         RADHIT

This second invocation of the RADHIT module is used by the pipeline to detect and flag cosmic ray events in linearized droop-corrected FITS data cubes. The module and its controlling parameters are exactly as described under RADHIT_SAT. The only difference is that in this invocation of RADHIT, bit flags (bit # 9) in dmask.fits for previously detected radhits are “erased” and radhit detection is begun anew. The resulting updated dmask.fits is used by SLOPE_FINDER to disregard radhit samples in the computation of the final slope image.
