244. Observing Control at the UKIRT
... Observing with the major instruments at the United Kingdom Infra-Red Telescope (UKIRT) is already semi-automated by using ASCII files to configure the instruments and then sequence a series of exposures and telescope movements to acquire the data. ... Using an off-line preparation system to create these has significantly improved observing efficiency, as also has the automatic, on-line data reduction system in use by one of the main instruments. ...

246. The STScI NICMOS Calibration Pipeline
... The NICMOS data reduction and calibration pipeline employs file formats and software architecture techniques that are new and different from what has been used for previous HST instruments. This paper describes the FITS file format used for NICMOS data, which includes error estimate and data quality arrays for each science image, and describes the approach used to associate multiple observations of a single target. ... This group of five data arrays is called an image set, or ``imset'' for short. ...

Next: Identification and Analysis of Binary Star Systems using Probability Theory . ... We present a computing code for modelling energy flux distributions, photometric indices and spectral line profiles of (non-)radially pulsating Main-Sequence stars. ... In the case of slowly rotating stars one can use the zero-rotation approximation to describe stellar pulsations. Such a model was used already by Cugier, Dziembowski & Pamyatnykh (1994) to study nonadiabatic observables of Cephei stars. ...
