Configuration fields

coaddName

Default
'deep'
Field type
str Field
Name of coadd

flags

Require that these flags, if available, are not set

minSN

Default
10.0
Field type
float Field
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

Default
3.0
Field type
float Field
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

Default
[]
Field type
str ListField
Priority-ordered list of bands for the merge.

pseudoFilterList

Default
['sky']
Field type
str ListField
Names of filters which may have no associated detection (N.b. should include MergeDetectionsConfig.skyFilterName)

snName
