After launch on 17 October 2002, 4:41 UT, the first part of the Commissioning Phase is dedicated to instrument activation and optimization of instrument configuration and nominally lasts for 3 weeks, i.e. up to 07 November 2002 (rev. 8). The subsequent Performance and Verification (PV) Phase consists of a set of observations lasting nominally 5 weeks (i.e. up to 16 December 2002) but actually extending until 30 December 2002, i.e. into the Nominal Mission Phase which is formally scheduled to start on 17 December 2002. The reason for extending PV phase operations lies in the long out-gassing phase for SPI after activation.
All data obtained during the PV phase up to including 16 December 2002 (nominal end of commissioning phase) are proprietary data for the INTEGRAL Science Working team (including instrument teams). PV phase observational data obtained after 16 December 2002 are publicly available via the ISDC.
