Context History (more history, all contexts)

Start Date Context Status Description
2020-10-09 jwst_0642.pmap operational The new NIRISS gain reference file was created using new Python scripts adapted from an IDL version of the same algorithm. This file is described in technical report JWST-STScI-005661. It was made using the same set of CV3 darks as the previous version of this file. IPC corrections differ slightly from the previous version due to newly calculated smaller corrections resulting in more pronounced epoxy void regions. Gaussian smoothing is applied after patching and IPC correction to remove edges between the 20x20 px tiles over which the gain is calculated. The mean gain over the illuminated region of the detector is 1.6221 plusminus 0.036, compared to the previous mean of 1.6246 plusminus 0.046 electrons per DN. The smoothing does not change either the overall mean or the four channel means by a significant amount.
2020-09-11 jwst_0641.pmap archived As indicated in the referenced JIRA issues, an error occurred during SOC 2.1 validation testing due to missing SUPERBIAS and DARK reference files for NRS1, SUB2048, and DISPERSER set to MIRROR. These dummy files were created to fill this gap in coverage. Reference files with real data will be submitted when such data becomes available.
2020-09-08 jwst_0640.pmap archived Initial delivery of the NIRISS pars-image2pipeline reference file. See JIRA issues CRDS-364, CCD-688, and JP-1246 for more details.
2020-08-28 jwst_0637.pmap archived Activate updates for NIRSpec dark current and default cube build parameters.
