On-orbit alignment and imaging performance of the HST advanced camera for surveys [PDF]

SPIE Proceedings, 2003
The Advanced Camera for Surveys (ACS), installed in the Hubble Space Telescope in March 2002, has significantly extended HST’s imaging capabilities. We describe the on-orbit optical alignment procedures and results, detailing the excellent image quality performance achieved. Comparison is made with the instrument specifications, ground test results and

Characterization and on-orbit performance of the Advanced Camera for Surveys CCDs

SPIE Proceedings, 2003
We present an overview of the Advanced Camera for Surveys (ACS) CCD detectors performance based on the ground testing and the calibration observations taken during the first four months of ACS operation. ACS has been installed into the Hubble Space Telescope in March 2002 and consists of three different cameras.

Advanced Camera for Surveys coronagraph on the Hubble Space Telescope

SPIE Proceedings, 2003
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 ...

Thermal design for the Advanced Camera for Surveys

SPIE Proceedings, 1998
The advanced camera for surveys (ACS) is a third generation science instrument scheduled for installation into the Hubble Space Telescope (HST) during the third servicing mission scheduled for 1999. ACS, along with the previously installed space telescope imaging spectrograph and near IR camera/multi-object spectrograph, consume significantly more ...

Stellar clusters in the nuclear regions of AGN with the Advanced Camera for Surveys

Astrophysics and Space Science, 2009
We explore the role of star clusters in the nuclear regions of galaxies through their connection with active galactic nuclei (AGN). Nuclear star clusters (NCs) are conspicuous in the centers of most nearby galaxies, all along the Hubble sequence. These clusters are probably the faint-end distribution of the central supermassive black holes (SMBHs) in ...

On-board image compression for the HST advanced camera for surveys

SPIE Proceedings, 1998
The wide-field camera in the advanced camera for surveys (ACS) produces very large 4096 by 4096 pixel images. We will have on-board image compression in order to reduce both the storage requirements at the telescope an the time to transmit the data to the ground. This is the first time on- board compression has been included in a Hubble Space Telescope

Optical performance verification and calibration of the HST Advanced Camera for Surveys

SPIE Proceedings, 1998
The advanced camera for surveys (ACS), scheduled for installation on the HST observatory in December 1999, is nearing completion at Ball Aerospace. This versatile camera, comprising 3 detector systems covering the wavelength range from the far UV through 1.1 micron, a large complement of filters, polarizers, prism and grism dispersers and a coronagraph,
