... CTE effects also produce extended ?tails? on hot pixels and cosmic rays that degrade images and spectra, creating an additional source of noise. ...
... The UDF consists of a single ultra-deep field that probes the tail of the reionization epoch and constrains the early evolution of the Universe. ...
... with a time scale of about 160 ± 60 seconds (different pixels show different decay rates), but there is also a long, roughly linear tail to the decay such that persistence from very bright sources remains detectable as much as 30 to 40 minutes after the ...
... This stability is in marked contrast to the evolving CTI (charge transfer inefficiency) found via photometry of external stellar images (e.g., Whitmore et al., 1999) and analysis of cosmic ray tails in dark frames (Riess et al., ...
... These and the corresponding FUV curves are nearly identical and show that the transmission of the COS apertures is essentially flat within the central ± 0.4 arcsec, then tails off in a non-linear but approximately symmetrical profile ( COS ISR 2010-09 ). ...
... The tail of FHWM values above 2.07 pixels in this figure occurs for data taken at a larger Sun angle (~115°) than the Sun angle for the remaining data (<90°). ...
