We invite submissions of Berkeley Visible Image Tube camera (BVIT) science commissioning programs to be carried out during the remainder of 2012 Semester 2 (i.e. up to 30 April 2013). A small allocation of time (~30h) is set aside for this and the purpose is to exercise the instrument and to test its performance on a variety of short programs. These programs will not be charged. BVIT is a visitor instrument built at the Space Science Laboratory of the University of California-Berkeley. It is a photon-counting camera with a ~1.9 arcmin field of view, capable of very high time resolution (millisec or microsec) photometry with a B, V, R or H-alpha filter. It can be used for objects with magnitudes ranging from V~12-20. Please note that BVIT does not provide high precision absolute photometry, but by observing nearby standard stars a flux intensity relative precision of ~ 5% can typically be obtained. Every detected photon is assigned a time of arrival and a (x,y) position on the detector, which allows an observer a high degree of post-acquisition data analysis flexibility. Users should also be aware that the instrument does not have an autoguider, although guidance checks can be done as needed by interrupting observations for ~1 min. Typically we can observe without guidance corrections for up to ~50 min, depending on the object position. Applications can be completed using the usual Phase 2 PIPT proposal form, selecting the "commissioning" button. The scientific justification needs not to be too detailed or lengthy and should simply summarize the particular regime or aspect of the instrument that will be tested, and the type of target to be observed and its parameters. The observing conditions and observation details can be entered with the PIPT, as usual. Proposals should ideally be submitted by 10 Feb and will be selected by the BVIT instrument team, in conjunction with SALT Astronomy Operations, with priority to those programs expanding the parameter space of the instrument.
