Glossary of terms

CIC

Clock-induced charge. A type of shot noise caused by clocking behavior in CCDs, of more concern when electron-multiplying. Also known as “spurious charge”. See Janesick’s Scientific Charge-coupled Devices, 7.1.2.

RON

Read-out noise. Noise inherent in the process of converting photoelectrons in a pixel to digital counts. Independent of signal level dependent on ADC and amplifier electronics and temperature. See Howell’s Handbook of CCD Astronomy, 3.4.

shmim

Shared-memory image. The unifying abstraction of CACAO inter-process communication, essentially a block of computer memory and a way to coordinate updates with other processes in the system.
