This WDdata repository contains combined HST Cycle 20 and Cycle 22 DA White
Dwarf (DAWD) photometry (GO 12967, 13711, P.I. Saha) and ground-based
spectroscopy. This data can be used together with the WDmodel to infer SEDs of the DAWDs from their
observed spectroscopy and photometry. The data are described in Calamida et al.
(2018, submitted) and the analysis in Narayan et al. (2018, submitted).
