Characterization Metric Report: Science Pipelines Version 13.0¶
Measured using validation_data_hsc, which consists of 8 HSC engineering images: 4 r-band, 2 i’-band, and 2 y-band.
Measurements were made on individual, separately-processed, single-frame images: Jointcal and/or meas_mosaic were not run.
For comparison, we provide the SRD required “minimum” value of each metric as defined in the Science Requirements Document (LPM-17), and, where available, the target for this release as defined in the Data Management Development Milestone Roadmap (LDM-240).
All values were computed using the examples/runHscTest.sh script in the validate_drp package.
Photometric Performance¶

procCalRep corresponds to requirement OSS-REQ-0275 (defined in LSE-30). All other photometric performance metrics follow LSS-REQ-0093 (LSE-29) and LPM-17 table 14.

Computational Performance¶
Computational performance metrics were not re-measured for this release. We expect no significant changes relative to the report on version 12.
