In August 2009, a sequence of events triggered by a corruption of on-board memory lead to the loss of the prime side electronics chain of HIFI. Since then, a significant effort has been made that has enabled a full recovery of the instrument using its redundant side electronics.
The special circumstances of HIFI's switch to redundant side operations, and resuming with a compressed Performance Verification phase and accelerated Observing Mode release, has involved the support of many others, together with the HIFI Calibration Scientists and Instrument Engineers. This includes KP team apprentices who have been variously present at the HIFI ICC in the Fall of 2009 and during the performance verification phase starting end-January 2010, and also the HIFI software development team who have been available at all times. AOT test planning has been done in consultation with the KP PIs coordinated by X. Tielens, Instrument P.I. F. Helmich, Project Manager P. Roelfsema, and with the Mission Scientist J. Cernicharo. These persons should be acknowledged, as having directly supported the flight qualification of HIFI as a science instrument.
