Retargetable subtasks¶
reserve¶
- Default
lsst.meas.algorithms.reserveSourcesTask.ReserveSourcesTask
- Field type
Reserve sources from fitting
Configuration fields¶
applyColorTerms¶
Apply photometric color terms to reference stars? One of: None: apply if colorterms and photoCatName are not None;
fail if color term data is not available for the specified ref catalog and filter.
- True: always apply colorterms; fail if color term data is not available for the
specified reference catalog and filter.
False: do not apply.
colorterms¶
- Data type
- Field type
Library of photometric reference catalog name: color term dict
fluxField¶
Name of the source instFlux field to use. The associated flag field (‘<name>_flags’) will be implicitly included in badFlags.
magErrFloor¶
- Default
0.0
- Field type
- Range
[0.0,inf)
Additional magnitude uncertainty to be added in quadrature with measurement errors.
match¶
- Data type
lsst.meas.astrom.directMatch.DirectMatchConfigWithoutLoader
- Field type
Match to reference catalog
nIter¶
number of iterations
nSigma¶
clip at nSigma
photoCatName¶
Name of photometric reference catalog; used to select a color term dict in colorterms. see also applyColorTerms
sigmaMax¶
maximum sigma to use when clipping
useMedian¶
use median instead of mean to compute zeropoint
