Flashlights: Prospects for constraining the initial mass function around cosmic noon with caustic-crossing events

Table A.1.

Strongly lensed arcs used in our current work observed in HFF clusters. Columns (1), (2), (3), and (4) represent the image cluster name ID, R.A., Dec., and source redshift of the lensed arc, respectively. Column (5) gives the ICL surface density near each lensed arc. Columns (6), (7), and (8) provide the star-formation rate (SFR), metallicity (Z), and dust extinction (A_V) for each arc estimated using BAGPIPES. Columns (9) and (10) list the average number of CCEs per visit in each arc for the top-heavy (α = 1.00) and Salpeter (α = 2.35) IMFs, respectively. For Abell 370, Abell S1063, MACS0416, and MACS1149, the coordinates and arc redshifts are taken from Lagattuta et al. (2019), Caminha et al. (2016), Richard et al. (2021), and Zitrin (2021), respectively, and references therein.
