Our current thinking is that (1) we do not sensor the raw data, (2) we instead make a custom pfsConfig for each PI, in which information of targets of other PIs is reasonably anonymous: (a) catId and objId are replaced with NULL or -1 or some other nonsense number, (b) ra and dec point the fiducial center of each cobra (i.e., ra + dec is different what we actually point to), and (c) pfiCenter and pfiNominal also point at the fiducial center. This does not make targets by other PIs completely anonymous but better than nothing. We also plan to (3) distribute the pipeline processed data for each PI through the science database, and (4) make an observatory policy that if you look at spectra other than your own, you will not be able use PFS in future runs. I am slightly worried that "(b)" might have some effect on the sky subtraction if we interpolate the sky line intensities acorss the field of view, but they probably do not vary significantly over a scale of 1 arcmin.
