Pixel-based CTI-correction for HST/STIS CCD data
Project description
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
