New Post-Analysis Tasks Available

Three new post-analysis tasks have been created to correct various kinds of STIS data. These tasks will be included in the upcoming fall STSDAS release (v3.6).

CTESTIS

IRAF/STSDAS task to correct measured data in STIS CCD photometry tables for CTE loss. Details.

MKTRACE

IRAF/STSDAS task to measure the orientation of the trace of a target in a spectroscopic image and to create a spectral trace table appropriate for that orientation. Details.

WX2D

IRAF/STSDAS task to rectify spectral images using an alternative interpolation algorithm to the bilinear interpolation used by the task "x2d". The latter is used during OTFR retrievals of STIS spectra. Details.
