Summary of the observations from programmes 1210 and 3215.
| Disperser | Prism | G140M | G395M |
|---|---|---|---|
| Filter | CLEAR | F070LP | F290LP |
| Spectral resolution R | 30–300 | 700–1500 | 700–1500 |
| Exp. time 1210 [h] | 18.7 | 4.7 | 4.7 |
| Exp. time 3215 [h] | 46.7 | 11.7 | 46.7 (37.4) (a) |
| Exp. time Total [h] | 65.4 | 16.4 | 51.5 (42.1) (a) |
Notes. These exposure times apply only to GS-z12; other targets in the two programmes may have different exposure times, depending on the mask allocation.
The last visit was affected by short circuits in the MSA (Rawle et al. 2022), and the true exposure time in PID 3215 is reduced to 37.4 h.
