Magnetic CVs in the UCT CCD CV Survey
An overview is given of all the magnetic CVs found in the UCT CCD CV Survey (Woudt & Warner 2001, 2002, 2003a). We have identified eight new candidate Intermediate Polars (IP), of which six are classical novae (RR Cha, DD Cir, AP Cru, V697 Sco, V373 Sct, and RXJ1039.7-0507). The two other candidate IPs are Aqr1 (2236+0052) and RXJ0944.5+0357. In addition, there are two probable Polars, namely V...
متن کاملNoise analysis for CCD-based ultraviolet and visible spectrophotometry.
We present the results of a detailed analysis of the noise behavior of two CCD spectrometers in common use, an AvaSpec-3648 CCD UV spectrometer and an Ocean Optics S2000 Vis spectrometer. Light sources used include a deuterium UV/Vis lamp and UV and visible LEDs. Common noise phenomena include source fluctuation noise, photoresponse nonuniformity, dark current noise, fixed pattern noise, and re...
متن کاملAn Algorithm for Correcting CTE Loss in Spectrophotometry of Point Sources with the STIS CCD
The correction for the change in sensitivity with time for the STIS CCD modes is complicated by the gradual loss of charge transfer efficiency (CTE) of the CCD. The amount of this CTE loss depends on time in orbit, the location on the CCD chip with respect to the readout amplifier, the stellar signal strength, and the background level. Primary constraints on our correction algorithm are provide...
