| Abstract: | The Large Synoptic Survey Telescope (LSST) is a large-aperture, wide-field,
ground-based survey system that will image the sky in six optical bands from
320 to 1050 nm, uniformly covering approximately $18,000$deg$^2$ of the sky
over 800 times. The LSST is currently under construction on Cerro Pach’on in
Chile, and expected to enter operations in 2022. Once operational, the LSST
will explore a wide range of astrophysical questions, from discovering "killer"
asteroids to examining the nature of Dark Energy.
The LSST will generate on average 15 TB of data per night, and will require a
comprehensive Data Management system to reduce the raw data to scientifically
useful catalogs and images with minimum human intervention. These reductions
will result in a real-time alert stream, and eleven data releases over the
10-year duration of LSST operations. To enable this processing, the LSST
project is developing a new, general-purpose, high-performance, scalable, well
documented, open source data processing software stack for O/IR surveys.
Prototypes of this stack are already capable of processing data from existing
cameras (e.g., SDSS, DECam, MegaCam), and form the basis of the Hyper-Suprime
Cam (HSC) Survey data reduction pipeline. |
