Overview

You can access this service using:

static -- static (i.e. prepared) data or custom client-side code; probably used to access ancillary files here
form -- allows access via an HTML form
scs.xml -- a standard SCS interface as defined by the IVOA to access catalog-type data; SCS clients use https://herschel-vos.phys.sussex.ac.uk/hsc_photoz/q/cone/scs.xml? to access the service

This service is published as follows:

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

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.
