Table 1
Available subarrays for bright object time-series (BOTS) observations.
| Subarray | Size [pixel] | tg [s] | texp [h] |
|---|---|---|---|
| SUB2048 | 32 × 2048 | 0.90156 | 32.8 |
| SUB1024A/B | 32 ×1024 | 0.45100 | 16.4 |
| SUB512 | 32 × 512 | 0.22572 | 8.22 |
| SUB512S | 16 × 512 | 0.14364 | 5.23 |
Notes. The subarray size is given in number of pixels along spatial × spectral axes. tg denotes the read time for a single group/frame in NRSRAPID mode (no frame averaging). texp is the maximum exposure time for 65 535 of the shortest possible integrations (ng = 1, tint(min) = 2 × tg) and will be longer for integrations with ng > 1. SUB1024A and SUB1024B are two distinct subarrays with different locations on the detectors, but with the same dimension and therefore identical frame times.
