The information in this registry is available as a VO service.
The service main address is:
http://svo2.cab.inta-csic.es/svo/theory/fps/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/fps/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/fps/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/fps/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:
- WavelengthRef (range)
- 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/fps/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/fps/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 A 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:
