ampEdgeInset

lsst.ip.isr.ampOffset.AmpOffsetConfig.ampEdgeInset

static

Initial value:

=  pexConfig.Field(
        doc="Number of pixels the amp edge strip is inset from the amp edge. A thin strip of pixels running "
        "parallel to the edge of the amp is used to characterize the average flux level at the amp edge.",

        default=5,
    )

Definition at line 31 of file ampOffset.py.

ampEdgeMaxOffset

static

Initial value:

=  pexConfig.Field(
