Hardware folks may find the following report of interest, which appeared on the astro-ph preprint server last week:
StarDICE I: sensor calibration bench and absolute photometric calibration of a Sony IMX411 sensor
Betoule et al, accepted for publication in A&A
Thanks for reposting this. I'm anticipating taking delivery any day now of a Moravian camera featuring the IMX411's (not so) little brother - the IMX461. Same pixels, just a smaller sensor. One of the praises I've repeatedly heard about these sensors is that dark current is extremely low, and reading this paper seems to confirm that. GEts me more excited to get the camera in and get it to work.
