Methods Documentation
-
calculate
(diaObjects, diaSources, filterDiaSources, filterName, **kwargs)¶ Compute fit a linear model to flux vs time.
- 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.
- diaObject
-
fail
(diaObject, columns, error=None)¶ Set diaObject position values to nan.
- Parameters
- diaObject
dict
Summary object to store values in.
- columns
list
ofstr
List of string names of columns to write a the failed value.
- error
BaseException
orNone
Error to pass. Kept for consistency with CatologCalculationPlugin. Unused.
- diaObject

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
CatalogCalculationPlugin
s must run withBasePlugin.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.
