Simlib_Minion: Simulated Observation Libraries for the LSST

Simlib_Minion is a set of simulated observation libraries derived from the LSST Operations Simulator baseline cadence 'minion_1016_sqlite.db'. The dataset contains four files summarizing observation conditions for Deep Drilling Fields (DDF) and Wide-Fast-Deep (WFD) fields, with and without nightly coadds, for use with the SNANA simulation code. It was generated by Rahul Biswas and collaborators using code from the OpSimSummary project.

Use Cases

• Simulating LSST observations of supernovae based on the provided signal-to-noise ratio (SNR) calculations.
• Planning survey strategies by analyzing the baseline cadence for Deep Drilling Fields and Wide-Fast-Deep fields.
• Generating synthetic light curves for variable objects using the nightly coadded observation libraries.
• Testing photometric pipeline performance under simulated LSST observing conditions.

Strengths

• Derived from the published LSST Operations Simulator baseline cadence 'minion_1016_sqlite.db'.
• Includes separate files for Deep Drilling Fields and Wide-Fast-Deep fields, with and without coadds.
• Signal-to-noise ratio calculations are provided, based on specific columns from the simulator output.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The generation procedure notes that atmospheric transmission differences due to airmass are neglected and field overlaps are not treated.

Collection Method

Processed using code from the OpSimSummary GitHub repository, with duplicate visits removed and SNR calculated.
