Meteorological data for the astronomical site at Dome A, Antarctica
Yi Hu, Zhaohui Shang, Michael C. B. Ashley +7
We present an analysis of the meteorological data collected at Dome A, Antarctica by the Kunlun Automated Weather Station, including temperatures and wind speeds at eight elevation…
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…
A new method of CCD dark current correction via extracting the dark information from scientific images
Bin Ma, Zhaohui Shang, Yi Hu +3
We have developed a new method to correct dark current at relatively high temperatures for Charge-Coupled Device (CCD) images when dark frames cannot be obtained on the telescope.…
Planetary Transit Candidates in the CSTAR Field: Analysis of the 2008 Data
Songhu Wang, Hui Zhang, Ji-Lin Zhou +26
The Chinese Small Telescope ARray (CSTAR) is a group of four identical, fully automated, static 14.5 cm telescopes. CSTAR is located at Dome A, Antarctica and covers 20 square degr…
