• 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.
