GOTO with the LSST Software Stack

These wiki pages describe our work in using the LSST Software Stack (LSS) to reduce and analyse GOTO data. Included in this wiki are:

  • instructions on how to install the LSST stack;
  • guides for providing the LSST stack with information about GOTO's cameras (via obs_goto);
  • guides to configure the data reduction and analysis steps (again, via the obs_goto);
  • the commands used to instruct the LSST stack to reduce and analyse GOTO data;
  • data products of the LSST stack and how to access them;
  • results from testing the LSST output on simulated data.

What the LSS can do

The LSS is being developed to process all of the data that will be generated by the LSST. This includes:

  • Logging incoming data and managing the filesystem;
  • Instrument signature removal (i.e., flat-fielding, bias-subtraction);
  • Astrometric and photometric calibration;
  • Background subtraction;
  • Source detection;
  • PSF measurement;
  • Measuring aperture, PSF, Kron, CModel, Petrovian, de Vaucoulier etc. photometry;
  • Image alignment, warping, and coaddition to obtain deeper observations;
  • Forced photometry;
  • Image differencing.
