Astronomical Data Analysis Software and Systems XIII ASP Conference Series, Vol. ... Skysoft is a YAASD (Yet Another Astronomical Software Directory), but with a different overall approach. To be useful, Skysoft needs to be a longlived pro ject, setting little pressure for maintenance, imposing a very low nuisance level to the developers community, and requiring a lowmaintenance cost. ... This site is designed so that software developers acquire more visibility because of astronomical context. ...

Astronomical Data Analysis Software and Systems XIII ASP Conference Series, Vol. ... During early flight operation, the Chandra X-ray Observatory's Advanced CCD Imaging Spectrometer (ACIS) suffered degradation of charge transfer inefficiency (CTI) due to radiation induced charge trapping. The ACIS front-illuminated detector CTI has significantly degraded over time with respect to the intrinsic energy resolution of the chips. ... We will discuss the impact of CTI on events, RMF and gain files. ...

... As part of our effort to enhance the calibration of STIS (a spectrograph on-board the Hubble Space Telescope), we have developed a model of the readout process for CCD detectors suffering from degraded charge transfer efficiency. ... Nevertheless the empirical corrections for STIS provide an ideal means of testing and calibrating the physical model, as the empirical corrections are essentially a distillation of what is to be learnt from the calibration data with respect to CTI. ...
