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
