VizieR Online Data Catalog: Largest main belt asteroids data (Vernazza+, 2021)
Abstract
The baseline observational strategy adopted for our large programme has been to image each target with SPHERE/ZIMPOL (i) around opposition to ensure an optimal spatial resolution (we restricted the observing period so that its angular diameter remained greater than at least 85% of that at opposition), (ii) every ~60° in rotation phase in order to obtain a satisfactory surface coverage, and (iii) with seeing conditions of better than 0.8" and an airmass of below 1.6 in order to ensure great observing conditions and thus high-quality data. To fulfil these criteria and given that large programmes have the highest priority at ESO, we performed our large programme entirely in service mode. We would like to stress that this strategy has been key to the success of our programme.
