All the raw PT data for the SDSS, organized by MJD, are available at http://www-sdss.fnal.gov/sdssdp/ptraw/ (standard SDSS access applies) All the processed PT data for SDSS, organized by MJD, are available a= t http://www-sdss.fnal.gov/~sdssdp/mtdata/dp/apo20/run/listed_by_mj= d/ (again, standard SDSS access applies) For the processed PT data, the corrected frames are generally *not* kept on disk. That said, there are some corrected frames available for mjd54498 and a few other nights; see, e.g., http://www-sdss.fnal.gov/~sdssdp/mtdata/dp/apo20/run/listed_by_mj= d/mjd54498/wcs-test-mdR-00378666.fit http://www-sdss.fnal.gov/~sdssdp/mtdata/dp/apo20/run/listed_by_mj= d/mjd54498/wcs-test-mdR-00378667.fit http://www-sdss.fnal.gov/~sdssdp/mtdata/dp/apo20/run/listed_by_mj= d/mjd54498/wcs-test-mdR-00378668.fit http://www-sdss.fnal.gov/~sdssdp/mtdata/dp/apo20/run/listed_by_mj= d/mjd54498/wcs-test-mdR-00378669.fit http://www-sdss.fnal.gov/~sdssdp/mtdata/dp/apo20/run/listed_by_mj= d/mjd54498/wcs-test-mdR-00378670.fit which are the u'g'r'i'z' corrected frames for the SDSS/SEGUE Secondar= y Patch 225B1. (Note: the WCS info in the FITS headers here does not take into cons= ideration the slight radial geometric distortion in the PT field-of-view, so ta= ke the coordinates in these image files as only accurate to a few arcsec, es= p. towards the edges of the images.) Publicly accessibly (i.e., no SDSS access restrictions) catalog data = for all the SDSS Secondary Patches can be found here: http://das.sdss.org/PT/ (see Davenport et al. 2007, AJ, 134, 2430; Tucker et al. 2006, Astronomische Nachrichten, 327, 821; and Hogg et al. 2001, 122, 2129) Best regards, Douglas Bruce Gillespie wrote: >=20 > New Science and Operations Proposals for the Photometric Telesco= pe: a=20 > solicitation >=20 >=20 >=20 > For nearly a decade, the 0.5-meter Photometric Telescope (PT) at Ap= ache=20 > Point Observatory has been used to accurately monitor atmospheric= =20 > extinction coefficients, which has been a mainstay for the=20 > high-precision photometric calibration of SDSS data.
