Hamburg Objective Prism Sky Surveys - Online Access

The server handling the Hamburg Objective Prism Sky Surveys gives access to the digitized data of the Hamburg Quasar Survey and of the Hamburg/ESO Survey (HES). The server provides two-dimensional images in FITS-, JPEG, Postscript and PDF-Format.

The area currently covered by the digitized HQS is restricted in declination to 0 < δ < 80° and in galactic latitude to |b| > 20°. In case that the chosen region appears on several plates compressed images are displayed, from which a high-resolution image can be selected. For the HES similar restrictions apply.

Please enter a position and an image size. The image size is restricted to 15 arc min (4.4 Mb). Because of the length of a spectrum a minimum size of 240 arc sec (HQS) and 600 arc sec (HES) is recommended.
