Filter Profile Service
An experiment about filter standardization in the VO

VO Filter Information service

The information in this registry is available as a VO service.

The service main address is:

http://svo2.cab.inta-csic.es/svo/theory/fps3/fps.php

There are three main ways of accessing the service:

Retrieving information about a filter knowing its ID

Just send an http query to the service specifying a filter ID as a parameter, for instance:

http://svo2.cab.inta-csic.es/svo/theory/fps3/fps.php?ID=2MASS/2MASS.H

you will receive a VOTable containing all the information about the filter including its transmission curve.

By default, calibration information in Vega System will be included. To obtain information in a different Magnitude System, use the corresponding PhotCalID.

Retrieving information about a filter and its calibration knowing PhotCalID

Just send an http query to the service specifying a PhotCalID as a parameter, for instance:

http://svo2.cab.inta-csic.es/svo/theory/fps3/fps.php?PhotCalID=2MASS/2MASS.H/AB

The PhotCalID can be built adding /Vega, /AB or /ST to a filter ID.

you will receive a VOTable containing all the information about the filter including its transmission curve and the calibration information in the corresponding system.

Searching for filters: SSAP-like service

The service works as a SSAP service if a tool wants to use it for finding filters with certain properties.

Capabilities. FORMAT=metadata.

http://svo2.cab.inta-csic.es/svo/theory/fps3/fps.php?FORMAT=metadata
will answer with a VOTable with a list of the parameters by which the database can be searched.

The currently available search parameters are:

  • WavelengthMean (range)
  • WavelengthEff (range)
  • WavelengthMin (range)
  • WavelengthMax (range)
  • WidthEff (range)
  • FWHM (range)
  • Instrument (value)
  • Facility (value)
  • PhotSystem (value)

Search queries

Range type parameters must be specified in queries as a couple of min,max values

For instance:

http://svo2.cab.inta-csic.es/svo/theory/fps3/fps.php?Instrument=BUSCA&WavelengthEff_min=1000&WavelengthEff_max=5000

or can also be specified with the ¶m=min/max sintaxis:

http://svo2.cab.inta-csic.es/svo/theory/fps3/fps.php?Instrument=BUSCA&WavelengthEff=1000/5000

in both cases the answer will be a VOTable with a list of the filters which instrument=BUSCA and with an effective wavelength between 1000 and 5000 Â with some of their properties and a link to the final Data Query with the corresponding transmission curve.

Verbosity

The service allows for an optional additional VERB parameter representing the level of verbosity desired. If not specified, maximum verbosity will be provided. Currently, the available values are:
