Notes. (a) Median resolution at mid of échelle order. (b) S/N per pixel in the continuum at the mid wavelength of each cross disperser. (c) Number N of individual spectra observed with PEPSI. (d) I/404 (e.g.,) means CD I with center wavelength 404 nm. The time series Oct. 14–16, 2016 was taken only in CD III.
