Abstrakt

This paper describes the raw data processing software of the Photodetector Array Camera and Spectrometer (PACS), an instrument implemented on the Herschel satellite to cope with its restricted downlink bandwidth. The instrument's high raw data rates require not only the use of highly specialized lossless compression algorithms, but also the execution of reduction steps that are usually performed on the ground.

In this context the on-board data reduction ranges from simple data rejection by quality criteria (e.g. glitches) to ramp fitting and integration steps. We show how the on-board software approaches this task, and discuss the critical interrelation with the HERSCHEL ground segment.
