◆ bisectFactor

lsst.meas.algorithms.dynamicDetection.DynamicDetectionConfig.bisectFactor
static
Initial value:
= Field(dtype=float, default=1.2,
doc="Factor by which to increase thresholds in brightMaskFractionMax loop.")

Definition at line 61 of file dynamicDetection.py.

◆ brightGrowFactor

lsst.meas.algorithms.dynamicDetection.DynamicDetectionConfig.brightGrowFactor
static
Initial value:
= Field(dtype=int, default=40,
doc="Factor by which to grow the footprints of sources detected in the "
"\"bright\" detections stage (want this to be large to mask wings of "
"bright sources).")

◆ brightMaskFractionMax

lsst.meas.algorithms.dynamicDetection.DynamicDetectionConfig.brightMaskFractionMax
static
Initial value:
= Field(dtype=float, default=0.95,
doc="Maximum allowed fraction of masked pixes from the \"bright\" "
"detection stage (to mask regions unsuitable for sky sourcess). "
"If this fraction is exeeded, the detection threshold for this stage "
"will be increased by bisectFactor until the fraction of masked "
"pixels drops below this threshold.")

Definition at line 55 of file dynamicDetection.py.

◆ brightMultiplier

lsst.meas.algorithms.dynamicDetection.DynamicDetectionConfig.brightMultiplier
static
Initial value:
= Field(dtype=float, default=2000.0,
doc="Multiplier to apply to the prelimThresholdFactor for the "
"\"bright\" detections stage (want this to be large to only "
"detect the brightest sources).")

◆ brightNegFactor

lsst.meas.algorithms.dynamicDetection.DynamicDetectionConfig.brightNegFactor
static
Initial value:
= Field(dtype=float, default=2.2,

static
Initial value:
= Field(dtype=float, default=0.02,
doc="Minimum fraction of the requested number of sky sources for dynamic "
"detection to be considered a success. If the number of good sky sources "
"identified falls below this threshold, a NoWorkFound error is raised so "
