The ZTF Galactic science working group is undertaking a 3-night experiment to perform nearly all-night deep drilling of three individual fields, one per night. The goal of these observations will be to both detect and resolve stellar variability on all timescales covered by the baseline of a full night (~11 hr in January), and to assess the completeness of SCoPE periodicty detections in regions of different stellar densities by comparing SCoPE periods with periods detected within the experimental observations. The goals prompting the observations of the secondary fields are to to assess the feasibility and scientific return of near-simultaneous photometric and spectroscopic survey observations and to detect new variable sources within the COSMOS field, which is also planned for deep-drilling observations with Rubin-LSST.
- Оbserving area: Three primary fields (two Galactic an one extra-galactic) & three secondary fields overlapping with the SDSS - V and COSMOS. All primary fields overlap with SCoPE.
- Filters: r
- Exposure: 30 sec
- Cadence: One primary and one secondary field per night
