outputCols	DiaObject column names output by the plugin.
plugType	Does the plugin operate on a single source or the whole catalog (str)? If the plugin operates on a single source at a time, this should be set to "single"; if it expects the whoe catalog, to "multi".

Methods Summary

calculate(diaObjects, diaSources, **kwargs)	Find if any DiaSource is flagged.
getExecutionOrder()	Used to set the relative order of plugin execution.

Attributes Documentation

needsFilter = False

This plugin requires a filter to be specified. Plugin’s using filter names usually deal with fluxes and only a sub-set of the DiaSource catalog. Plugins that to not use the filter name usually run over a value common across all observations/detections such as position.

outputCols = ['flags']

DiaObject column names output by the plugin. DiaCalculationTask should raise an error if another pluging is run output to the same column. Output columns should be defined in the DPDD/cat/Apdb schema. Filter dependent columns should be specified without the filter name perpended to them. eg psfFluxMean instead of u_psfFluxMean.

plugType = 'multi'

Does the plugin operate on a single source or the whole catalog (str)? If the plugin operates on a single source at a time, this should be set to "single"; if it expects the whoe catalog, to "multi". If the plugin is of type "multi", the fail method must be implemented to accept the whole catalog. If the plugin is of type "single", fail should accept a single source record.

Methods Documentation

calculate(diaObjects, diaSources, **kwargs)

Find if any DiaSource is flagged.

Set the DiaObject flag if any DiaSource is flagged.

Parameters

diaObjectdict

Summary object to store values in and read ra/dec from.

**kwargs

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

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

All plugins must implement this method with an appropriate run level
