Exposure Time Calculator
An exposure time calculator (ETC) is currently being developed. This will include a graphical interface. Preliminary and conservative estimates are reported below for the three HRMOS spectral ranges.
SNR per resolution element for F4V-, G2V, and K4V-type stars (left upper panel, right upper left and bottom panels, respectively) as a function of G magnitudes (Vega system) for 1 hr of exposure time (airmass 1, dark sky condition, seeing=0.8”).
