Caption: Figure 4.
Number of unique SV and main-survey tiles in DR1 as a function of the night (see Table 4). Note that tiles can be observed on multiple nights and that the vertical dashed line indicates the start of the main survey on 2021 May 14. The large gap in observations between 2021 July 10 and 2021 September 20 was due to a major upgrade of the focal-plane electronics.
