Pixel-based correction for Charge Transfer Inefficiency in the Hubble Space Telescope Advanced Camera for Surveys
Charge Transfer Inefficiency (CTI) due to radiation damage above the Earth’s atmosphere creates spurious trailing in Hubble Space Telescope (HST) images. Radiation damage also creates unrelated warm pixels – but these happen to be perfect for measuring CTI. We model CTI in the Advanced Camera for Surveys (ACS)/Wide Field Channel and construct a physically motivated correction scheme. This opera...
متن کاملThe Advanced Camera for Surveys Coronagraph on the Hubble Space Telescope
The Advanced Camera for Surveys (ACS) was installed in the Hubble Space Telescope (HST) during Servicing Mission 3B in early 2002. It includes a High Resolution Camera (0.025 arcsec/pixel) with a selectable coronagraphic mode. Because it was added after construction began on the instrument, this classical Lyot coronagraph must operate on the uncorrected, spherically aberrated beam from HST. The...
متن کاملDetection of Planets with the Hubble Space Telescope Advanced Camera for Surveys
Under favourable circumstances direct planet detection will be feasible with the new Advanced Camera for Surveys, due for launch on the Hubble Space Telescope in 2001. This may be achieved through direct imaging using the ‘Aberrated Beam Coronagraph’ or through precise astrometric and photometric measurement of appropriate candidates. The α Cen triple star system, and nearest stars to the Sun, ...
متن کاملHubble Space Telescope Advanced Camera for Surveys Coronagraphic Observations of the Dust Surrounding Hd 100546
We presentHSTACS coronagraphic observations of HD 100546, a B9.5 star, 103 pc away from the Sun, taken in the F435W, F606W, and F814W bands. Scattered light is detected up to 1400 from the star. The observations are consistent with the presence of an extended flattened nebula with the same inclination as the inner disk. The well-known ‘‘spiral arms’’ are clearly observed and trail the rotating ...
متن کاملThe COSMOS Survey: Hubble Space Telescope / Advanced Camera for Surveys (HST/ACS) Observations and Data Processing
We describe the details of the Hubble Space Telescope (HST) Advanced Camera for Surveys / Wide Field Channel (ACS/WFC) observations of the COSMOS field, including the data calibration and processing procedures. We obtained a total of 583 orbits of HST ACS/WFC imaging in the F814W filter, covering a field that is 1.64 degrees2 in area, the largest contiguous field ever imaged with HST. The media...
