Retargetable subtasks¶
No subtasks.
Configuration fields¶
coaddName¶
Name of coadd
connections¶
- Data type
lsst.pipe.base.config.MergeMeasurementsConfigConnections- Field type
Configurations describing the connections of the PipelineTask to datatypes
flags¶
- Default
['base_PixelFlags_flag_interpolatedCenter', 'base_PsfFlux_flag', 'ext_photometryKron_KronFlux_flag', 'modelfit_CModel_flag']- Field type
Require that these flags, if available, are not set
minSN¶
If the S/N from the priority band is below this value (and the S/N is larger than minSNDiff compared to the priority band), use the band with the largest S/N as the reference band.
minSNDiff¶
If the difference in S/N between another band and the priority band is larger than this value (and the S/N in the priority band is less than minSN) use the band with the largest S/N as the reference band
priorityList¶
Priority-ordered list of filter bands for the merge.
pseudoFilterList¶
Names of filters which may have no associated detection (N.b. should include MergeDetectionsConfig.skyFilterName)
saveLogOutput¶
Flag to enable/disable saving of log output for a task, enabled by default.
saveMetadata¶
Flag to enable/disable metadata saving for a task, enabled by default. Deprecated: This field is deprecated and will be removed after v26.
snName¶
Name of flux measurement for calculating the S/N when choosing the reference band.
