Methods Documentation

data_from_svo(query, cache=True, timeout=None, error_msg='No data found for requested query')

Get data in response to the query send to SVO FPS. This method is not generally intended for users, but it can be helpful if you want something very specific from the SVO FPS service. If you don’t know what you’re doing, try get_filter_index, get_filter_list, and get_transmission_data instead.

Parameters:

querydict

Used to create a HTTP query string i.e. send to SVO FPS to get data. In dictionary, specify keys as search parameters (str) and values as required. List of search parameters can be found at http://svo2.cab.inta-csic.es/theory/fps/fps.php?FORMAT=metadata

error_msgstr, optional

Error message to be shown in case no table element found in the responded VOTable. Use this to make error message verbose in context of the query made (default is ‘No data found for requested query’)

cachebool

Cache the results? Defaults to True

Returns:

astropy.table.table.Table object

Table containing data fetched from SVO (in response to query)

get_filter_index(wavelength_eff_min=<Quantity 0. Angstrom>, wavelength_eff_max=<Quantity 1.79769313e+308 Angstrom>, **kwargs)

Get master list (index) of all filters at SVO Optional parameters can be given to get filters data for specified Wavelength Effective range from SVO

Parameters:

wavelength_eff_minQuantity having units of angstrom, optional

Minimum value of Wavelength Effective (default is 0 angstrom)

wavelength_eff_maxQuantity having units of angstrom, optional

Maximum value of Wavelength Effective (default is a very large quantity FLOAT_MAX angstroms i.e. maximum value of np.float64)

kwargsdict

Passed to data_from_svo. Relevant arguments include cache

Returns:

astropy.table.table.Table object

Table containing data fetched from SVO (in response to query)

get_filter_list(facility, instrument=None, **kwargs)

Get filters data for requested facilty and instrument from SVO

Parameters:

facilitystr

Facilty for filters

instrumentstr, optional

Instrument for filters (default is None). Leave empty if there are no instruments for specified facilty

kwargsdict

Passed to data_from_svo. Relevant arguments include cache

Returns:

astropy.table.table.Table object

Table containing data fetched from SVO (in response to query)

get_transmission_data(filter_id, **kwargs)

Get transmission data for the requested Filter ID from SVO

Parameters:

filter_idstr

Filter ID in the format SVO specifies it: ‘facilty/instrument.filter’. This is returned by get_filter_list and get_filter_index as the filterID column.

kwargsdict

Passed to data_from_svo. Relevant arguments include cache

Returns:

astropy.table.table.Table object

Table containing data fetched from SVO (in response to query)
