Exposure Time Calculator

Exposure Time Calculator

OSU has developed a calculator to determine exposure times for MODS Imaging ONLY:

An ETC for spectroscopic modes is in development. In the meantime, exposure time estimates can be made using the zeropoints which are given on the MODS Sensitivities page.
