Receipt: # 5065-3 Comments at submission 5 (latest): There were still concerns with the target acquistion for visits 31 and 32 (AzV 398 COS FUV). While the field stars were considered safe, AzV 398 itself was quite closer to the brightness limit. To alleviate this, I switched to COS spectroscopic target acquisition just for these two visits. Comments at submission 4: Changes have been made to resolve potential safety issues with the COS ACQ exposures. Visits 11 (AzV 023 COS) and 21 (AzV 214 COS) now use mirror B + BOA, and an increased integration time of around 240s. For visits 31 and 32 (AzV 398 COS), the same setting would require significantly more exposure time (almost 700s). Instead, we set up mirror A + BOA (exposure time 39s), and checked the two nearby sources for which the BOT provided warnings. We expect these two stars to be about 10x as faint as the target (AzV 398), based on SWIFT UVOT UVW2 photometry. Some of the visit labels have changed for consistency. Comments at submission 3: One of the 53 allocated orbits went unused at the previous submission. This resubmission uses the remaining orbit for the AzV 214 COS visit, where 2 orbits are now used (one FP-POS3 and one FP-POS4) instead of 1 (which was half FP-POS3 and half FP-POS4). Note that the STIS observations remain unchanged, and have already been reviewed by Dan Welty. Comments at submission 2 (Tue Sep 03 19:33:37 GMT 2024) Updating according to Change Request 92938, which includes the following changes. Substitution of one of the targets, 2DFS0699, with 2DFS3030, provided there are no duplications. Revision of the proposed signal-to-noise requirements to SNR = 25 at 1250 Angstrom for COS observations, and SNR = 13 at 2050 Angstrom for the STIS observations. Redistribution of the total allocated 53 orbits among your targets as follows: AzV-023: COS - 2, STIS - 3; AzV-214: COS - 1, STIS - 3; AzV-398: COS - 6, STIS - 16; 2DFS3030: COS - 4, STIS - 18. 934951779 ----- Attempting Submission 2 (Tue Sep 03 19:33:37 GMT 2024) ----- HST Phase II Proposal 17823 successfully submitted.

So far, 17 extinction curves have been measured for the SMC, and most of these deviate strongly from those observed in the Milky Way, being steeper and exhibiting a small or nonexistent bump feature at 2175 A. The dust could therefore be fundamentally different under the low-metallicity conditions (0.2 solar) of the SMC, and we aim to study how the composition of dust grains plays a role in these differences. Depletions of gas-phase metals are a key observable to infer constraints on the dust grain composition, and have been measured for 18 SMC sightlines. However, a systematic study of extinction curves and depletion is currently not possible, because the existing SMC extinction curve and depletion samples share only 3 sightlines. We propose COS/FUV and STIS/NUV spectroscopic observations at medium resolution towards 4 stars in the SMC, for which high-quality extinction curves are already available. These data will be used to measure the depletions of the key constituents of dust, and expand the depletion+extinction sample size from 3 to 7. With this increase in sample size, we will be able to explore the relation between UV extinction curves and the dust composition for the first time in the SMC. These sightlines also extend the existing SMC depletion sample to higher column densities (1e22 cm-2), thereby probing the accretion of gas-phase metals by dust grains at higher densities. We will investigate the relation between extinction curves and the composition of dust grains -- as measured by depletions -- in the Small Magellanic Cloud. Depletions of gas-phase metals have been measured for 18 SMC sightlines. However, the existing SMC extinction curve and depletion samples share only 3 sightlines. We propose COS/FUV and STIS/NUV spectroscopic observations towards 4 stars in the SMC, for which high-quality extinction curves are already available, and expand the depletion+extinction sample size from 3 to 7. The 4 targets will be observed with deep COS/FUV G130M (1291) and STIS/NUV-MAMA E230M (1978) spectroscopy. The 53 orbits allocated to this program, will be distributed to achieve the following estimated SNR: For COS, SNR >= 25 at 1250 A. This can be achieved in 1 - 6 orbits per source. For STIS, SNR >= 13 at 2050 A. This can require long exposure times. The observations have been structured in visits of 3 orbits each, as recommended here: https://hst-docs.stsci.edu/stisihb/chapter-2-special-considerations-for-cycle-32/2-6-scheduling-efficiency-and-visit-orbit-limits. The COS visits start with an NUV imaging target acquisition, with a mirror and aperture combination that depends on the brightness. Then, the G130M/1291 exposures are taken for multiple orbits. We set up a mix of FP-POS3 and FP-POS4 observations, to achieve the benefits of dithering. This is achieved by setting a separate FP-POS per visit or per orbit. The estimated exposure time available is around 2400 s for the first orbit in a visit, and 2700 s for subsequent visits. The STIS visits start with a spectroscopic target acquisition, using the CCD in combination with the F28x50LP long pass slit, which is appropriate for the brightness of all sources. Then three long exposures with E230M/1978 orbit are performed, one exposure per orbit. Buffer times have been set according to the fill time reported by the ETC. The estimated exposure time available is around 2300 s for the first orbit in a visit, and 2800 s for subsequent visits. As per Change Request 92938, the target 2DFS0699 has been replaced by 2DFS3030. All team members are experts in interstellar dust. D.
