MIRI CAL-003 RSCD Correction
Abstract
The MIRI detectors must be calibrated for a variety of effects, including the reset switch charge decay (RSCD). The RSCD leads to a difference between the slope of the first integration in a series compared to later integrations, and it depends significantly on the illumination level of the previous integration. This calibration activity obtains data to characterize the RSCD and improves the corrective algorithms applied by the calibration pipeline. By using the MIRI internal calibration lamps with different imaging filters and the three MRS grating settings, we will obtain a variety of illumination levels. These data will be combined with darks to constrain and improve the correction algorithm.
This calibration program is provisional and may change in response to system developments and the final science program.- Publication:
