Service Documentation

The CCD700 archive contains spectra exposed with 700mm camera of coude spectrograph at Ondrejov observatory 2m Perek telescope, Czech Republic. The spectrograph works in first and second order and typical spectral resolving power is 13000 in first order around Halpha region and twice in Hbeta. The propriatory period is set to one year after the exposure with possible exceptions. All spectra were taken by the team of Stellar department of the Astronomical Institute of the Czech Academy of Sciences, Astronomical Institute of the Faculty of Math anf Physics of Charles University, Prague, and Department of Theoretical Physics and Astrophysics of the Faculty of Science, Masaryk University, Brno. All spectra were reduced in IRAF by M. Slechta. VO technical help by Jiri Nadvornik.

Overview

You can access this service using:

dlget -- a datalink interface letting specialized clients retrieve parts of datasets or discover related data. You use this kind of service exclusively in combination with a pubdid, usually via a direct link.
form -- allows access via an HTML form
dlmeta -- a datalink interface for discovering access options (processed data, related datasets...) for a dataset. You usually need a publisherDID to use this kind of service. For special applications, the base URL of this service might still come handy: http://vos2.asu.cas.cz/ccd700/q/sdl/dlmeta

This service is not published. This can mean that it was deemed too unimportant, for internal use only, or is just a helper for a published service. Equally likely, however, it is under development, abandoned in development or otherwise unfinished. Exercise caution.

Other services provided on the underlying data include:

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

Name	Table Head	Description	Unit	UCD
ID	Id	The pubisher DID of the dataset of interest	N/A	meta.id;meta.main

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.

Name	Table Head	Description	Unit	UCD	Verb. Level
ID	PubDID	Publisher data set id; this is an identifier for the dataset in question and can be used to retrieve the data.	N/A	meta.id;meta.main	1
access_url	URL	URL to retrieve the data or access the service.	N/A	meta.ref.url	1
service_def	Svc. Type	Identifier for the type of service if accessURL refers to a service.	N/A	meta.code	1
description	Description	More information on this link	N/A	meta.note	1
semantics	What?	What kind of data is linked here? Standard identifiers here include science, calibration, preview, info, auxiliary	N/A	meta.code	1
content_type	MIME	MIME type for the data returned.	N/A	meta.code.mime	1
content_length	Size	Size of the resource at access_url	byte	phys.size;meta.file	1
error_message	Why not?	If accessURL is empty, this column gives the reason why.	N/A	meta.code.error	20
