  abstract =	 " The aim of this work is to find a dedicated concept
                  for efficient compression of Herschel-PACS control
                  data. These data represent the setting parameters of
                  the different instruments within PACS, which have to
                  be transmitted with scientific data for diagnosis
                  purpose. As these control data have a deterministic
                  variability and because of the limited telemetry
                  bandwidth, it was decided to lossless compress the
                  control data for efficient exploitation of the
                  downlink. In this report, an analysis of the control
                  data has been made and a dedicated compression
                  concept with different entropy coders has been
                  developed and tested on simulated and real data. The
                  obtained results have been evaluated and compared to
                  a state-of-the-art codec.",
