Information on Service 'HELP spectroscopic redshift catalogue'

For a list of all services and tables belonging to this service's resource, see Information on resource 'HELP spectroscopic redshift catalogue'

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:

• 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/specz/q/cone/scs.xml? to access the service

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.
