Table information for ''


This table is available for ADQL queries and through the TAP endpoint.

Resource Description: A table containing reference data for HII regions. We also give a source code to compute abundances and electron temperatures in HII regions from strong emission lines.

For a list of all services and tables belonging to this table's resource, see Information on resource 'Reference HII Regions for Abundance Determination'

Citing this table

This table has an associated publication. If you use data from it, it may be appropriate to reference 2012MNRAS.424.2316P (ADS BibTeX entry for the publication) either in addition to or instead of the service reference.

To cite the table as such, we suggest the following BibTeX entry:

  title={Reference {HII} Regions for Abundance Determination},
  author={Pilyugin, L.S. and Grebel, E.K. and Mattsson, L.},
  howpublished={{VO} resource provided by the {GAVO} Data Center}

Resource Documentation

The data available here can be used the calculation of the abundances and temperatures in one or many HII regions.

We have prepared a FORTRAN program to do this, available in the archive Cmethod.tar.gz

The archive includes a README explaining how to use the program.
