1709. System Interfaces to the STIS Calibration Pipeline
... The routine processing of STIS data in the calibration ``pipeline" requires an interrelated set of software tasks and databases developed and maintained by many groups at STScI. We present the systems-level design of this calibration pipeline from the perspective of the STIS instrument group at STScI. We describe the multiple interfaces to the pipeline processes that the STIS group works across in an effort to provide for the routine calibration of STIS data. ... For example, the STIS group: . ...

1710. A Software Package for Automatic Reduction of ISOPHOT Calibration Data
... Also the measured signals are affected by detector transients, altering the final results considerably. We present the design and the main features of a software package, developed in order to support the absolute calibration of the instrument. ... In case the fit is not successful, the average of the last 30% of the data is taken as the final signal. ... The two different symbols represent individual calibrations of the final background signals, using the first or the second FCS-signal. ...
