Problems with twilight/supersky flat-field for wide-field robotic telescopes and the solution
Peng Wei, Zhaohui Shang, Bin Ma +3
Twilight/night sky images are often used for flat-fielding CCD images, but the brightness gradient in twilight/night sky causes problems of accurate flat-field correction in astron…

The nonlinear photon transfer curve of CCDs and its effects on photometry
Bin Ma, Zhaohui Shang, Lifan Wang +3
The photon transfer curve (PTC, variance vs. signal level) is a commonly used and effective tool in characterizing CCD performance. It is theoretically linear in the range where ph…
