Abstract:
This work is about the design and development of a standalone tool for the decompression of data from the Photodetector Array Camera and Spectrometer (PACS), one of the instruments housed inside the HERSCHEL Space Observatory (HSO). This is a part of an on-ground processing software package, with the purpose to provide an instrument for collecting, assembling, decompressing and later analyzing the data fragments received from the telescope. The work is done in JAVA programming language for simplicity, portability, reliability and a distributed computing. Furthermore, JAVA is object-oriented. Object-oriented programming provides greater flexibility, modularity and reusability. Thus it is easy to maintain/extend the on-ground processing tool for different or further compression algorithms or general upgrades. Within this work, we developed a scientific software tool for the processing of the received data from the HSO/PACS instrument. This software tool is designed and tested for PACS data but not limited for astronomical applications. The on-ground processing concept can easily be adapted for other applications (Medical imaging, Telecommunication ...etc). Results from the evaluation of the software with real and virtual test data are given at the end of this report.
