Data processing

Important

Data Preview 2 has not yet been released. This website is currently under development.

A high-level overview of the Data Release Processing (DRP) steps which generated the data products. All processing was done with the LSST Science Pipelines.

Summary

A summary of the DRP processing stages.

• Summary

Instrument signature removal (ISR)

Corrects the raw images for the effects of the telescope and detector.

• Instrument signature removal (ISR)

Calibration

Generates the science-ready processed visit images.

• Image calibration

Coaddition

Generates the deep coadd and template images.

• Image coaddition

Source detection and measurement

Generates catalogs of detected sources and measurements of their properties.

• Source detection and measurement

Difference image analysis

Runs image subtraction to generate difference images and associated detection catalogs.

• Difference image analysis (DIA)

Moving objects processing

Links detected sources into moving objects and generates Solar System catalogs.

• Solar System processing (SSP)
