  3. Subdetector Reports
    • FCAL - Adesh has put in updated pedestals (same values for mode 7+8 data) and gains (different for mode 7,8) for Spring 2015 data. The difference between the gains for mode 7 and 8 data is understood to be due to a mismatch between the algorithm used by the firmware in mode 7 and the emulation in sim-recon for mode 8. Addressing this difference requires the major rewrite of the emulation code that is in progress. Adesh tried modifying the configuration of the emulation in a private version of sim-recon, but did not find an improvement in the resolution, so the larger FCAL resolution is still not understood. The hardware gain balancing has been done, default software gains of 1 will be uploaded to the CCDB for the current run period.
    • BCAL - No news.
    • CDC - Constants to correct for wire sag have been added to the CCDB. Mike is still checking his new drift time constants before adding these to CCDB/sim-recon. He has derived these from beam data, so the calibration codes can be incorporated to the calibration challenge.
