Abstract The Rosetta COSIMA calibration data contains the operational history of the 72 dust collecting substrates from the installation to the beginning of the Rosetta hibernation. The operations are either spectra, total intensity, heating, imaging or grain lists. The data is groubed by the substrate and time. The aim of the data has been the instrument calibration and operational functionality, not statiscally good substrate background spectra
Description Data Set Overview = This dataset contains data from COSIMA instrument in the Rosetta spacecraft. The set covers the substrate history from the calibration period of the instrument starting 2002-05-29 up to the payload checkout #13 2010-12-05. During the calibration period the instrument was operated with several software versions and for test purposes the operations were not always nominal. The substrate histories are anyway considered to be complete. During the first commissioning period from 2004-03-02 to 2004-06-06 the substrates from the target holder #D8 covering the dust inlet was stored. During the second commissioning period from 2004-09-06 to 2004-10-16 the first ever in space secondary ion mass spectra were generated. These can be found from the substrate #1C2 data. During the passive payload checkouts (PC) no science data was generated. The target holder #C2 was to be lifted to test the target manipulator unit. This failed in PC1 and PC3 due to hardware anomaly. Due to spacecraft telemetry problem, this history is not available from PC2 either. Test images from empty COSISCOPE slot were taken in all payload checkouts. All the substrates were also imaged in space to be used later as initial reference images. During the active checkouts the main operational concentration was to heal the baddly behaving ion emitter A. During those operations some spectra was acquired, but without intention to generate really scientifically usable background spectra from the substrates. Parameters The primary measured parameter is the time of flight mass spectrum of a grain, ion events collected for 131072 time bins, each 1.953125 ns in length. For data selection purposes, three individual time windows can be selected for each generated spectrum. In addition or instead, a peak list separating the organic and inorganic peaks can be generated. For quantitive analysis and gain optimisation, instead of i...

The spacecraft carries a Rosetta Lander, named Philae, to the nucleus and deploys it onto its surface. A brief description of the mission and its objectives can be found in the Rosetta Science Management Plan [RO-EST-PL-0001] and in papers [GLASSMEIERETAL2007A]. A detailed description of the mission analysis can be found in the Consolidated Report on Mission Analysis [RO-ESC-RP-5500], the ROSETTA User Manual [RO-DSS-MA-1001], and the flight Operations Plan [RO-ESC-PL-...
