J. Kissel, K. Izumi, E. Hall for the CAL Team We've been studying the discrepancies between the GDS low-latency pipeline (which produces H1:GDS-CALIB_STRAIN) vs what comes out of the CAL-CS front-end real-time calibration (which produces H1:CAL-DELTAL_EXTERNAL_DQ). Please check out G1500750 for a discussion on this.
