Observed spectra and their fitted models from DEEP2 survey

For a list of all services and tables belonging to this service's resource, see Information on resource 'SSA service for DEEP2 spectra'

Overview

You can access this service using:

ssap.xml -- a standard SSAP interface as defined by the IVOA to access spectral or time-series data; SSAP clients use http://rcsed-vo.sai.msu.ru/specphot/deep2.ssap.q/ssa/ssap.xml? to access the service
form -- allows access via an HTML form

This service is published as follows:

Within the set(s) local with the renderer ssap.xml

local means it is listed on our front page, ivo_managed means it has a record in the VO registry, gavo means it is within GAVO's service registry.
