For a list of all services and tables belonging to this service's resource, see Information on resource '1M-WideField Images'

Overview

You can access this service using:

scs.xml -- a standard SCS interface as defined by the IVOA to access catalog-type data; SCS clients use http://data.xao.ac.cn/nsone/q/web/scs.xml? to access the service
form -- an interface for web browsers through an HTML form

This service is published as follows:

Within the set(s) ivo_managed with the renderer dali
Within the set(s) ivo_managed,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.

Input Fields

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

SR	Search Radius	Search radius	deg	N/A
verb	Verbosity	Exhaustiveness of column selection. VERB=1 only returns the most important columns, VERB=2 selects the columns deemed useful to the average user, VERB=3 returns a table with all available columns.	N/A	N/A

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

Name	Table Head	Description	Unit	UCD
accref	Product key	Access key for the data	N/A	meta.ref.url
accsize	File size	Size of the data in bytes	byte	VOX:Image_FileSize
date_obs	Date_obs	Observation date	d	time.obs
dec	Dec	Area center Declination ICRS	deg	pos.eq.dec;meta.main
obsURL	Download	Link to retrieve data	N/A	N/A
ra	RA	Area center RA ICRS	deg	pos.eq.ra;meta.main
telescope	Telescope	The name of telescope.	N/A	instr.tel

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
accref	Product key	Access key for the data	N/A	meta.ref.url	1
accsize	File size	Size of the data in bytes	byte	VOX:Image_FileSize	11
mime	Type	MIME type of the file served	N/A	meta.code.mime	20
id	Obs. Id	Artificial identifier of the observation	N/A	meta.id;meta.main	20
ra	RA	Area center RA ICRS	deg	pos.eq.ra;meta.main	20
dec	Dec	Area center Declination ICRS	deg	pos.eq.dec;meta.main	20
object	Target Object	Object observed	N/A	meta.id;src	20
exposure_time	Exp. Time	Exporsure Time	s	N/A	20
telescope	Telescope	The name of telescope.	N/A	instr.tel	20
