Service Documentation

This catalogue is a compendium of spectroscopic redshifts gathered by Matthew Smith for HELP work package 6. The per field catalogue from WP6 were concatenated in an all-sky catalogue adding a 'field' column, removing the few sources out of HELP coverage and adding a unique identifier to each source based on the location.

Overview

You can access this service using:

This service is published as follows:

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):

NameTable Head DescriptionUnitUCD
DEC Delta (ICRS) Declination (ICRS decimal) deg pos.eq.dec
field Field Name of the field in HELP survey N/A meta.id;obs.field
hscs_pos Position/Name Coordinates (as h m s, d m s or decimal degrees), or SIMBAD-resolvable object N/A N/A
hscs_sr Search radius Search radius in arcminutes N/A N/A
MAXREC Match limit Maximum number of records returned. Pass 0 to retrieve service parameters. N/A N/A
RA Alpha (ICRS) Right Ascension (ICRS decimal) deg pos.eq.ra
RESPONSEFORMAT Output Format File format requested for output. N/A meta.code.mime
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
z_qual z_qual Redshift quality flag (see note) N/A meta.code.qual;src.redshift

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.

NameTable Head DescriptionUnitUCD
agn_flag agn_flag AGN flag set to 1 for confirmed AGN. N/A meta.code.class
dec Dec Declination (J2000) deg pos.eq.dec;meta.main

z_source z_source Source catalogue of the redshift (see note) Note 1 N/A meta.ref;src.redshift
z_spec z_spec Spectroscopic redshift N/A src.redshift

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.

NameTable Head DescriptionUnitUCD Verb. Level

Note 1

As the source of the redshift can be multiple surveys, the source number is byte encoded. The encoding depends on the field.

Note 2

The quality flag is designated using the method from Colless et al. (2001) method (as the GAMA database uses these values). The quality flag is ranked on a five-point scale, with the interpretation:

1 means no redshift could be estimated
2 means a possible, but doubtful, redshift estimate
3 means a probable redshift (notionally 90 per cent confidence)
4 means a reliable redshift (notionally 99 per cent confidence)
5 means a reliable redshift and a high-quality spectrum

Note that this quality parameter is determined entirely by the subjective judgement of the user. A small number of galaxies have a quality flag to -1 which means no quality flag was available.

Note 3

Some survey provide additional information on the source that is presented encoded in the note column. The meaning depends on the field.

For COSMOS:

1 COSMOS photometric redshift not consistant to within 0.1(1+z)
2 No COSMOS photometric redshift available
3 COSMOS photometric redshift consistant to within 0.1(1+z)
4 One line wither Halpha or [OII] 3727 best guess
5 One line wither Halpha or [OII] 3727 best guess, only consistent with COSMOS photo-z after redshift switched to alternate
6 Broad Line AGN
7 COSMOS and GAMA reshift have clashed, GAMA value given.
