NoRHClient#

class sunpy.net.dataretriever.NoRHClient[source]#

Bases: GenericClient

Provides access to the Nobeyama RadioHeliograph (NoRH) averaged correlation time series data.

Uses this https archive hosted by the NoRH Science Center.

Queries to NoRH should specify either 17GHz or 34GHz as a Wavelength.

Examples

>>> import astropy.units as u
>>> from sunpy.net import Fido, attrs as a
>>> results = Fido.search(a.Time("2016/1/1", "2016/1/2"),
...                       a.Instrument.norh, a.Wavelength(17*u.GHz))  
>>> results  
<sunpy.net.fido_factory.UnifiedResponse object at ...>

Attributes Summary

baseurl

info_url

This should return a string that is a URL to the data server or documentation on the data being served.

pattern

Methods Summary

post_search_hook(exdict, matchdict)

This method converts 'tca' and 'tcz' in the url's metadata to a frequency of '17 GHz' and '34 GHz' respectively.

pre_search_hook(*args, **kwargs)

Converts the wavelength specified in the query to its representation in the url which can be used by the scraper.

register_values()

This enables the client to register what kind of Attrs it can use directly.

Methods Documentation

post_search_hook(exdict, matchdict)[source]#

This method converts ‘tca’ and ‘tcz’ in the url’s metadata to a frequency of ‘17 GHz’ and ‘34 GHz’ respectively.

classmethod pre_search_hook(*args, **kwargs)[source]#

Converts the wavelength specified in the query to its representation in the url which can be used by the scraper.
