The Sloan Digital Sky Survey data acquisition system, and early results

PDF Version Also Available for Download.

Description

The Sloan Digital Sky Survey will systematically map one- quarter of the sky, producing detailed images in five color bands and determining the positions and absolute bright- nesses of more than 100 million celestial objects. It will also measure the redshifts of a million selected galaxies and of 100,000 quasars, yielding a three-dimensional map of the universe through a volume one hundred times larger than that explored to date. The SDSS collaboration is currently in the process of commissioning the 2.5-meter survey tele- scope. We describe the data acquisition system used to record the survey data. This system consists of ... continued below

Description

The Sloan Digital Sky Survey will systematically map one- quarter of the sky, producing detailed images in five color bands and determining the positions and absolute bright- nesses of more than 100 million celestial objects. It will also measure the redshifts of a million selected galaxies and of 100,000 quasars, yielding a three-dimensional map of the universe through a volume one hundred times larger than that explored to date. The SDSS collaboration is currently in the process of commissioning the 2.5-meter survey tele- scope. We describe the data acquisition system used to record the survey data. This system consists of twelve sin- gle board computers and their associated interfaces to the camera and spectrograph CCD electronics, to tape drives, and to online video displays, distributed among several VME crates. A central UNIX computer connected to the VME crates via a vertical bus adapter coordinates the sys- tem and provides the interface to telescope operations. We briefly discuss results from the observing runs to date and plans for the archiving and distribution of data.
