lsst.ip.diffim

The lsst.ip.diffim module provides algorithms and utilities for astronomical image differencing and transient detection.

Overview of lsst.ip.diffim

Using lsst.ip.diffim

Production pipelines

This package is used in production pipelines like lsst.ap.pipe and lsst.drp.pipe, designed for processing large collections of survey data.

For an example of how the two primary PipelineTasks in this package (AlardLuptonSubtractTask and DetectAndMeasureTask) are used in a production pipeline, see ap_pipe/pipelines/ApPipe.yaml.

Single frame processing

Single image frame usage can be carried out by importing the diffim as a library of tasks, as the following example shows:

from lsst.ip.diffim import subtractImages

...
subtract_task = subtractImages.AlardLuptonSubtractTask()

subtraction = subtract_task.run(
   warped_template, science, science_source_catalog)

For source detection a similar pattern works:

from lsst.ip.diffim import DetectAndMeasureTask

...
detect_task = DetectAndMeasureTask()

detect_and_measure = detect_and_measure_task.run(
   science, subtraction.matchedTemplate, subtraction.difference)

Contributing

lsst.ip.diffim is developed at https://github.com/lsst/ip_diffim. You can find Jira issues for this module under the ip_diffim component.
