Data processing

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.

For details see DP1 paper reference.

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)
