Methods Documentation

emptyMetadata() → None¶: Empty (clear) the metadata for this Task and all sub-Tasks.

getAssociationInfo(inputFile, calib, calibType)¶

Determine the information needed to create a dataId for this dataset.

Parameters:

inputFilelsst.resources.ResourcePath: Original file containing the dataset. Used for log messages.
caliblsst.ip.isr.IsrCalib: The calibration dataset to study.
calibTypestr: The calibration type/version name.

Returns:

instrumentNamestr: Instrument this dataset belongs to.
whereClausestr: Butler query “where” that will find the exposure with matching dataId.
bindingdict [str: str]: Binding values for whereClause.
logIdstr: A string (or dataset convertable to string) to be used in downstream logs.

getDatasetType()¶

Return the DatasetType to be ingested.

Returns:

datasetTypelsst.daf.butler.DatasetType: The datasetType for the ingested data.

getDestinationCollection()¶

Return the collection that these datasets will be ingested to.

Returns:

collectionNamestr: The collection the data will be ingested to.

getFullMetadata() → TaskMetadata¶

Get metadata for all tasks.

Returns:

metadataTaskMetadata: The keys are the full task name. Values are metadata for the top-level task and all subtasks, sub-subtasks, etc.

Notes

The returned metadata includes timing information (if @timer.timeMethod is used) and any metadata set by the task. The name of each item consists of the full task name with . replaced by :, followed by . and the name of the item, e.g.:

topLevelTaskName:subtaskName:subsubtaskName.itemName

using : in the full task name disambiguates the rare situation that a task has a subtask and a metadata item with the same name.

getFullName() → str¶

Get the task name as a hierarchical name including parent task names.

Returns:

fullNamestr

The full name consists of the name of the parent task and each subtask separated by periods. For example:

The full name of top-level task “top” is simply “top”.
The full name of subtask “sub” of top-level task “top” is “top.sub”.
The full name of subtask “sub2” of subtask “sub” of top-level task “top” is “top.sub.sub2”.

getName() → str¶

Get the name of the task.

Returns:

taskNamestr: Name of the task.

See also

getFullName: Get the full name of the task.

getTaskDict() → dict[str, weakref.ReferenceType[lsst.pipe.base.task.Task]]¶

Get a dictionary of all tasks as a shallow copy.

Returns:

taskDictdict: Dictionary containing full task name: task object for the top-level task and all subtasks, sub-subtasks, etc.

classmethod makeField(doc: str) → ConfigurableField¶

Make a lsst.pex.config.ConfigurableField for this task.

Parameters:

docstr: Help text for the field.

Returns:

configurableFieldlsst.pex.config.ConfigurableField: A ConfigurableField for this task.

Examples

Provides a convenient way to specify this task is a subtask of another task.

Here is an example of use:

class OtherTaskConfig(lsst.pex.config.Config):
    aSubtask = ATaskClass.makeField("brief description of task")

makeSubtask(name: str, **keyArgs: Any) → None¶

Create a subtask as a new instance as the name attribute of this task.

Parameters:

namestr

Brief name of the subtask.

**keyArgs

Extra keyword arguments used to construct the task. The following arguments are automatically provided and cannot be overridden:

config.
parentTask.

Notes

The subtask must be defined by Task.config.name, an instance of ConfigurableField or RegistryField.

readCalibFromFile(inputFile)¶

Read the inputFile, and determine its calibration type and read it.

Parameters:

inputFilelsst.resources.ResourcePath: File to be read to check ingestibility.

Returns:

caliblsst.ip.isr.IsrCalib: The appropriately subclassed implementation for this calibration type.
calibTypestr: The calibration type/version name.

run(locations, run=None, file_filter='Photodiode_Readings.*txt$|_photodiode.ecsv$|Electrometer.*fits$|EM.*fits$', track_file_attrs=None)¶

Ingest calibration data into a Butler data repository.

Parameters:

filesiterable over lsst.resources.ResourcePath: URIs to the files to be ingested.
runstr, optional: Name of the RUN-type collection to write to, overriding the default derived from the instrument name.
skip_existing_exposuresbool, optional: If True, skip photodiodes that have already been ingested (i.e. raws for which we already have a dataset with the same data ID in the target collection).
track_file_attrsbool, optional: Control whether file attributes such as the size or checksum should be tracked by the datastore. Whether this parameter is honored depends on the specific datastore implementation.

Returns:

refslist [lsst.daf.butler.DatasetRef]: Dataset references for ingested raws.

Raises:

RuntimeError: Raised if the number of exposures found for a photodiode file is not one

timer(name: str, logLevel: int = 10) → Iterator[None]¶

Context manager to log performance data for an arbitrary block of code.

Parameters:

namestr: Name of code being timed; data will be logged using item name: Start and End.
logLevelint: A logging level constant.
