The lapRun table defines and groups the reprocessing of a single projection cell

|| name            || type   || note ||
|| lap_id          || int    ||             ||
|| seq_id          || int    || ||
|| tess_id         || string || ||
|| projection_cell || string || ||
|| filter          || string || ||
|| state           || string || 'new' if still running, 'full' if complete ||
|| registered      || date   || date lapRun was defined ||
|| fault           || int    || ||
|| label           || string || ||
|| quick_sass_id   || int    || stackAssociation id of the quickstack for this run ||
|| final_sass_id   || int    || stackAssociation id of the final stack for this run ||
|| dist_group      || string || distribution group to give to all dependents ||

The lapExp table defines the pool of exposures, and associates them with the lapRuns that use them

|| name       || type   || note ||
|| lap_id     || int    || ||
|| exp_id     || int    || ||
|| chip_id    || int    || chip_id of the processing of exp_id used in this run ||
|| pair_id    || int    || chip_id of the companion exposure for a pairwise diff ||
|| private    || bool   || this exp_id/chip_id set is only available to this run ||
|| pairwise   || bool   || this chip_id will be pairwise diffed against pair_id ||
|| active     || bool   || this exp_id/chip_id is currently in use by this run ||
|| data_state || string || ||

The lapSequence table groups a set of lapRuns together into a complete sample of the sky.

|| name        || type    || note ||
|| seq_id      || integer ||             ||
|| description || string  ||             ||
