aTmCam

The aTmCam (Atmospheric Transmission Monitoring Camera) is a calibration system to monitor atmospheric transmission in real-time, designed to enable improved photometric calibration of data acquired by large-area imaging surveys. It is designed to enable the improved photometric calibration of data acquired by the Dark Energy Camera (DECam) at the Víctor M. Blanco 4-meter Telescope.
