STIS Calibration Enhancement: Wavelength Calibration and CTI
نویسندگان
چکیده
The Instrument Physical Modeling Group in the Space Telescope European Co-ordinating Facility has undertaken to examine aspects of STIS calibration and develop physical model based solutions where appropriate. Here we discuss two such aspects and the status of the model based solutions. The first concerns the derivation of dispersion solutions for the echelle spectroscopy modes. The second corrects two dimensional CCD data (imaging and spectroscopic) for the effect of imperfect charge transfer in the read out process.

STIS Model Based Charge Transfer Inefficiency Correction
The STE-CF Calibration Enhancement effort for the Space Telescope Imaging Spectrograph (STIS) aims to improve data calibration via the application of physical modelling techniques. As part of this effort we have developed a model of the STIS CCD readout process that is able to correct STIS data for charge transfer inefficiency (CTI). The model itself is described in some detail in earlier ISRs....
متن کاملImprovements to the STIS First Order Spectroscopic Point Source Flux Calibration
During the operational lifetime of STIS, the primary emphasis of throughput measurements was the accurate determination of broad band point source fluxes observed using the low dispersion modes at the center of the 52X2 aperture, including measurement of time-dependent changes in sensitivity. We will review the current status and accuracy of this primary flux calibration, and discuss the remain...
متن کاملCalstis6: Extraction of 1-D Spectra in the STIS Calibration Pipeline
This report updates and extends the discussion of STIS ISR 97-02 on the extraction of 1-D spectra performed by calstis6 in the STIS calibration pipeline. Calstis6 processes flatfielded, 2-D science images to produce one-dimensional spectra using an unweighted extraction algorithm. The resultant fluxand wavelength-calibrated spectra are stored in 3-D binary tables.
متن کاملFOS Post-Operational Archive and STIS Calibration Enhancement
The first part of this report summarizes the scientific quality enhancement for FOS/BL data—the Post-Operational Archive project. Part two describes the status and planning for the follow up, a calibration enhancement for the 66,095 data sets obtained with STIS between 1997 and 2001 when it was operated using “Side 1 electronics.”
متن کاملSTIS Flux Calibration
The low dispersion STIS spectrophotometric flux calibration must account for all instrumental non-linearities and all changes in sensitivity with time and temperature. An empirical algorithm for CCD Charge Transfer Efficiency (CTE) is presented along with the wavelength dependent sensitivity changes. Precise STIS spectrophotometry includes corrections for CTE losses as large as 20% for faint si...
