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.
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.
