Methods Documentation

calculate(diaObjects, diaSources, filterDiaSources, filterName, **kwargs)

Compute min/max of the point source fluxes.

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 filterName.

filterName : str

Simple, string name of the filter for the flux being calculated.

**kwargs

Any additional keyword arguments that may be passed to the plugin.

fail(diaObject, columns, error=None)

Set diaObject position values to nan.

Parameters:

diaObject : dict

Summary object to store values in.

columns : list of str

List of string names of columns to write a the failed value.

error : BaseException or None

Error to pass. Kept for consistency with CatologCalculationPlugin. Unused.

classmethod getExecutionOrder()

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

CatalogCalculationPlugins must run with BasePlugin.DEFAULT_CATALOGCALCULATION or higher.

All plugins must implement this method with an appropriate run level

getLogName()

static getTransformClass()

Get the measurement transformation appropriate to this plugin.

This returns a subclass of transforms.MeasurementTransform, which may be instantiated with details of the algorithm configuration and then called with information about calibration and WCS to convert from raw measurement quantities to calibrated units. Calibrated data is then provided in a separate output table.

Notes

By default, we copy everything from the input to the output without transformation.
