Information on Service 'SuperCOSMOS Sources'

Further access options are discussed below

The SuperCOSMOS data primarily originate from scans of the UK Schmidt and Palomar POSS II blue, red and near-IR sky surveys. The ESO Schmidt R (dec < -17.5) and Palomar POSS-I E (dec > -17.5) surveys have also been scanned and provide an early (1st) epoch red measurement. Mirrored here is the source table containing four-plate multi-colour, multi-epoch data which are merged into a single source catalogue for general science exploitation. Within the GAVO DC, some column names have been adapted to local customs (primarily positions, proper motions).

Overview

You can access this service using:

form -- an interface for web browsers through an HTML form
scs.xml -- a standard SCS interface as defined by the IVOA to access catalog-type data; SCS clients use https://dc.zah.uni-heidelberg.de/supercosmos/q/s/scs.xml? to access the service

This service is published as follows:

Within the set(s) ivo_managed with the renderer dali
Within the set(s) local with the renderer form
Within the set(s) ivo_managed with the renderer scs.xml

local means it is listed on our front page, ivo_managed means it has a record in the VO registry.

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
