Notes. The columns list the NIRSpec ID; the ID of the closest match within 02$\[0^{\prime\prime}_\cdot2\]$ in the NIRCam data release catalogue (Rieke et al. 2023); RA and Dec supplied to the eMPT for target allocation, and for path loss determination; the priority class (see Table 1); the spectroscopic redshift, zspec and associated flag, as described here ‘A’ – derived from S/N> 5 emission lines detected in the R1000 grating, ‘B’ – derived from S/N> 5 emission lines detected in the prism observations, ‘C’ – derived from spectral break and/or lower significance emission lines; the average intra-shutter offset of the source in arcseconds over the multiple pointings; the number of exposures (nods and dithers) for the prism and for each of the gratings (G140M, G235M, G395M, G395H), where a single exposure has duration 1400.5s; the priority from HST data only; and citations detailing where the source has been found before. The citation key is as follows: Targets marked with a ‘N’ were NIRCam-based, and do not have a counterpart in our HST-based catalogue. The majority of the remaining targets have counterparts in our HST-based catalogue drawn from one of Skelton et al. (2014), Guo et al. (2013), Rafelski et al. (2015), and/or Whitaker et al. (2019). Targets which do not have a counterpart in any of these catalogues are marked with an asterisk, representing only a small number of targets. Numbers indicate additional reference catalogues which were used for identifying and prioritising potential targets. Targets which are not NIRCam-based (not an ‘N’), flagged with an asterisk (i.e. not from one of the four large catalogues listed prior), and do not have a numerical reference listed were drawn from Coe et al. (2006); this represents only six targets in Priority Class 9.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
