Exposure Time Estimation

, Updated

The MAROON-X Integration Time Calculator (ITC) is available here.

Below are example SNR plots for two stars observed during the commissioning phase in December 2019. These examples show the measured SNR in each order for the combined flux of all three object fibers. These data are not extinction corrected, neither are the telluric absorption features removed or the flux from overlapping orders summed up. They give a snapshot of what to expect from a typical observation.
