Utilities needed to correct for Charge Transfer Inefficiency (CTI) in the Hubble Space Telescope (HST) STIS CCD.
Scripts installed in shell:
- stis_cti -- Runs CTI correction on raw files, handling super-dark creation
- archive_dark_query -- Determines component darks needed to remake a super-dark
For more information, type:
stis_cti --help
Python usage:
import stis_cti stis_cti.stis_cti(...)
Other utilities:
- stis_cti.StisPixCteCorr(...) -- Code to run pixel-based CTI-correction on intermediate products
- stis_cti.viable_ccd_file(...) -- Test to see which FITS files on which to run the correction
- stis_cti.archive_dark_query(...) -- Utility to query MAST for needed component darks
- stis_cti.custom_superdark_info() -- Print information on manually creating/implementing a corrected super-dark
