◆ calculate()

lsst.meas.base.diaCalculationPlugins.MaxSlopeDiaPsfFlux.calculate ( self,
diaObjects,
diaSources,
filterDiaSources,
band,
** kwargs )
Compute the maximum ratio time ordered deltaFlux / deltaTime.

Parameters
----------
diaObject : `dict`
    Summary object to store values in.
diaSources : `pandas.DataFrame`
    DataFrame representing all diaSources associated with this
    diaObject.
filterDiaSources : `pandas.DataFrame`
    DataFrame representing diaSources associated with this
    diaObject that are observed in the band pass ``band``.
band : `str`
    Simple, string name of the filter for the flux being calculated.
**kwargs
    Any additional keyword arguments that may be passed to the plugin.

◆ getExecutionOrder()

lsst.meas.base.diaCalculationPlugins.MaxSlopeDiaPsfFlux.getExecutionOrder ( cls)
Used to set the relative order of plugin execution.

    The values returned by `getExecutionOrder` are compared across all
    plugins, and smaller numbers run first.

    Notes
    -----
    `CatalogCalculationPlugin`\s must run with
    `BasePlugin.DEFAULT_CATALOGCALCULATION` or higher.

    All plugins must implement this method with an appropriate run level
