Function Documentation

◆ fluxErrName()

lsst.pipe.tasks.functors.fluxErrName ( col)
Append _instFluxErr to the column name if it doesn't have it already.

Definition at line 789 of file functors.py.

◆ fluxName()

lsst.pipe.tasks.functors.fluxName ( col)
Append _instFlux to the column name if it doesn't have it already.

Definition at line 782 of file functors.py.

◆ init_fromDict()

lsst.pipe.tasks.functors.init_fromDict ( initDict,
basePath = 'lsst.pipe.tasks.functors',
typeKey = 'functor',
name = None )
Initialize an object defined in a dictionary.

The object needs to be importable as f'{basePath}.{initDict[typeKey]}'.
The positional and keyword arguments (if any) are contained in "args" and
"kwargs" entries in the dictionary, respectively.
This is used in `~lsst.pipe.tasks.functors.CompositeFunctor.from_yaml` to
initialize a composite functor from a specification in a YAML file.

Parameters
----------
initDict : dictionary
    Dictionary describing object's initialization.
    Must contain an entry keyed by ``typeKey`` that is the name of the
    object, relative to ``basePath``.
basePath : str
    Path relative to module in which ``initDict[typeKey]`` is defined.
typeKey : str
    Key of ``initDict`` that is the name of the object (relative to
    ``basePath``).

◆ mag_aware_eval()

lsst.pipe.tasks.functors.mag_aware_eval ( df,
expr,
log )
Evaluate an expression on a DataFrame, knowing what the 'mag' function
means.

Builds on `pandas.DataFrame.eval`, which parses and executes math on
DataFrames.

Parameters
----------
df : ~pandas.DataFrame
    DataFrame on which to evaluate expression.

expr : str
    Expression.
