PhotodiodeIngestTask

class lsst.obs.lsst.PhotodiodeIngestTask(butler, instrument, config=None, **kwargs)

Bases: Task

Task to ingest photodiode data into a butler repository.

Parameters:
configPhotodiodeIngestConfig

Configuration for the task.

instrumentInstrument

The instrument these photodiode datasets are from.

butlerButler

Writable butler instance, with butler.run set to the appropriate RUN collection for these datasets.

**kwargs

Additional keyword arguments.

Methods Summary

emptyMetadata()

Empty (clear) the metadata for this Task and all sub-Tasks.

getDatasetType()

Return the DatasetType of the photodiode datasets.

getFullMetadata()

Get metadata for all tasks.

getFullName()

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

getName()

Get the name of the task.

getTaskDict()

Get a dictionary of all tasks as a shallow copy.

makeField(doc)

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

makeSubtask(name, **keyArgs)

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

run(locations[, run, file_filter, ...])

Ingest photodiode data into a Butler data repository.

timer(name[, logLevel])

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

Methods Documentation

emptyMetadata() None

Empty (clear) the metadata for this Task and all sub-Tasks.

getDatasetType()

Return the DatasetType of the photodiode datasets.

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.

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.

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

Ingest photodiode 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.

lsst.utils.timer.logInfo

Implementation function.

Examples

Creating a timer context:

with self.timer("someCodeToTime"):
    pass  # code to time
