Image Details
Caption: Figure 1.
Top panels: representative seasonal observing schedule for NEID Earth Twin Survey target stars. We schedule sets of time-sensitive observations (red; P0) to bracket the observing season, high-cadence observations (blue; P1) in the middle of each season to sample rotationally modulated stellar signals, and long-baseline observations (yellow; P2) to improve phase coverage. Bottom panels: enacted schedules for each of the first 3 yr of the survey. In gray, we show standard star observations and supplemental NETS observations, including P3 and P4, that do not strictly follow our seasonal and nightly observing schemes.
