  2. PSU CALDB file status • CALDB items stored in Excel file • Converted to FITS format under Linux/Solaris • Managed with SCCS • Sent via FTP to ISAC • Bad Pixel Table • Currently we have one hot pixel: • (DETX, DETY) = (454, 391) • Currently we have one partially blocked column: • DETX = 454 • DETY = 392 – 602 • Bad pixel table uploaded to instrument • Bad pixel tables sent to ISAC XRT Team Meeting – ASDC – September17-18, 2003 (Page 2)

  3. PSU CALDB file status • Linearity • Linearity fitted to Panter calibration data • Gain coefficients calculated, put into FITS format • FITS files sent to ISAC • NOTE: current definition of Gain file assumes linearity in energy • We may need to modify this to allow nonlinear energy response • Bias Information • Image mode: Amp 2, Low gain, 134 DN • Photodiode mode: Amp 1, High gain • 114.2 DN at Panter • 129.5 DN now • Not sure why this has changed • FITS files sent to ISAC • Background files • Data processing in progress at PSU • We expect background to be small – users can assume it is negligible for proposal purposes.
