OSSE Data Flow and Analysis
Abstract
The Oriented Scintillation Spectrometer Experiment (OSSE) consists of four large volume NaI detectors that are optimized to observe gamma-rays in the 0.05 - 10.0 MeV energy band. Each detector can be oriented independently and has a wide variety of observation and telemetry modes, leading to a complex data analysis environment. The OSSE data analysis task is rendered even more complicated by the on-orbit environment, which exhibits a rich set of variations as a function of energy, point direction, orbital phase and total time in orbit. Since the typical OSSE signal to noise ratio is very low, understanding and accounting for background variations is a critical and complex task. In order to deal with the OSSE data analysis challenge, a system of databases and software have been developed. These include a series of well defined data products that are handled first by a production data analysis system performing routine processing and then by a scientific analysis system which allows individual scientists to examine and manipulate OSSE data.
