ConfigClass = DecamCpIsrConfig | |
Perform ISR task using Community Pipeline Calibration Products MasterCal. The CP MasterCal products have butler dataset types cpBias and cpFlat, different from the LSST-generated calibration products (bias/flat).

exposure, | |||

) |
Apply bias correction in place DECam bias products have been trimmed and are smaller than the raw exposure. The size of edge trim is computed based on the dimensions of the input data. Only process the inner part of the raw exposure, and mask the outer pixels as EDGE. Parameters ---------- exposure : `lsst.afw.image.Exposure` Exposure to process. biasExposure : `lsst.afw.image.Exposure` Bias exposure.
def lsst.obs.decam.decamCpIsr.DecamCpIsrTask.flatCorrection | ( | self, | |
exposure, | |||
flatExposure | |||
) |
Apply flat correction in place. DECam flat products have been trimmed and are smaller than the raw exposure. The size of edge trim is computed based on the dimensions of the input data. Only process the inner part of the raw exposure, and mask the outer pixels as EDGE. Parameters ---------- exposure : `lsst.afw.image.Exposure` Exposure to process. flatExposure : `lsst.afw.image.Exposure` Flatfield exposure.
