Contribution
It provides the first measurements of the Fano factor in CCD systems and offers recommendations for improving faint object observation strategies.
Findings
Fano factor measurements reveal CCD signal distortions.
Assessment of CCD signal processing quality.
Suggested optimal observation strategies for faint objects.
Abstract
Factors distorting the statistics of photocounts when acquiring objects with low fluxes were considered here. Measurements of the Fano factor for existing CCD systems were conducted. The study allows one to conclude on the quality of the CCD video signal processing channel. The optimal strategy for faint object observations was suggested.
