Background
Xavier Prochaska of UCO/Lick Observatory has assembled
measurements of ESI echellette-mode throughput dating back to 2002
into a web
page that features plots and tables with the following
information:
- Instrumental zero point (AB mag) for
1 e- s-1 pix-1 as a
function of wavelength
- Instrumental zero point (AB mag) for
1 e- s-1 Å-1 as a
function of wavelength
- End-to-end efficiency (throughput including telescope and
instrument) as a function of wavelength
