Remote data (sunpy.net)

sunpy.net contains a lot of different code for accessing various solar physics related web services. This submodule contains many layers. Most users should use Fido, which is an interface to multiple sources including all the sources implemented in dataretriever as well as vso and jsoc. Fido can be used like so:

>>> from sunpy.net import Fido, attrs as a
>>> results = Fido.search(a.Time("2012/1/1", "2012/1/2"), a.Instrument.lyra)  
>>> files = Fido.fetch(results)

sunpy.net Package

Classes

Scraper(pattern[, regex])

sunpy.net.attrs Module

‘attrs’ are parameters which can be composed together to specify searches to sunpy.net.Fido. They can be combined by using logical and (&) and logical or (|) operations to construct very complex queries.

For example you could combine two instruments using or (|) with a time specification and a sample cadence using:

>>> import astropy.units as u
>>> from sunpy.net import Fido, attrs as a
>>> a.Time("2011/01/01", "2011/01/02") & (a.Instrument.aia | a.Instrument.hmi) & a.Sample(1*u.day))

In addition to the core attrs defined here, other sunpy clients also provide attrs specific to them, under:

Classes

Time(start[, end, near])

Specify the time range of the query.

Instrument(value)

Specifies the Instrument name for the search.

Wavelength(wavemin[, wavemax])

Level(value)

Specifies the data processing level to search for.

The type of Extent; for example, "FULLDISK", "SYNOPTIC", "LIMB", etc.

Sample(value)

Detector(value)

Resolution(value)

Physobs(value)

VSO

VSOQueryResponseTable([data, masked, names, ...])

Class Inheritance Diagram

Inheritance diagram of sunpy.net.vso.vso.VSOClient, sunpy.net.vso.table_response.VSOQueryResponseTable

sunpy.net.vso.attrs Module

Attributes that can be used to construct VSO queries.

Attributes are the fundamental building blocks of queries that, together with the two operations of AND and OR (and in some rare cases XOR) can be used to construct complex queries. Most attributes can only be used once in an AND-expression, if you still attempt to do so it is called a collision. For a quick example think about how the system should handle Instrument(‘aia’) & Instrument(‘eit’).

Classes

Extent(x, y, width, length, atype)

Specify the spatial field-of-view of the query.

Field(fielditem)

A subclass of the value attribute.

Pixels(value)

Pixels are (currently) limited to a single dimension (and only implemented for SDO data) We hope to change this in the future to support TRACE, Hinode and other investigations where this changed between observations.

Filter(value)

This attribute is a placeholder for the future.

Quicklook(value)

Retrieve 'quicklook' data if available.

PScale(value)

Pixel Scale (PSCALE) is in arc seconds.

Dataretriever

sunpy.net.dataretriever Package

The sunpy.net.dataretriever submodule is a framework for downloading data from “simple” web sources such as HTTP or FTP servers. Although it could be used for more complex services as well.

All these subclasses are then registered with the sunpy.net.Fido factory class, so do not need to be called individually.

sunpy.net.hek.attrs Module

Attributes that can be used to construct HEK queries. They are different to the VSO ones in that a lot of them are wrappers that conveniently expose the comparisons by overloading Python operators. So, e.g., you are able to say AR & AR.NumSpots < 5 to find all active regions with less than 5 spots. As with the VSO query, you can use the fundamental logic operators AND and OR to construct queries of almost arbitrary complexity. Note that complex queries result in multiple requests to the server which might make them less efficient.

sunpy.net.attr Module

Allow representation of queries as logic expressions. This module makes sure that attributes that are combined using the two logic operations AND (&) and OR (|) always are in disjunctive normal form, that is, there are only two levels ­- the first being disjunction and the second being conjunction. In other words, every combinations of attributes looks like this: (a AND b AND c) OR (d AND e).

Walkers are used to traverse the tree that results from combining attributes. They are implemented using functools.singledispatch modified to dispatch on the second argument to the function.

Please note that & is evaluated first, so A & B | C is equivalent to (A & B) | C.
