Query for Solar Orbiter data using the Wavelength attribute

sunpy-soar provides convenient methods to construct queries using a.Wavelength for several different remote sensing instruments available through the SOAR. In this guide, we will demonstrate how we can query data using a.Wavelength for different instruments. For instruments EUI, METIS and SOLOHI we get query results in form of wavelength. However, at this time we cannot search for wavelengths for instruments SPICE, PHI, and STIX as this information is not yet available in the SOAR.

For instruments EUI, METIS and SOLOHI passing a single Wavelength

When a single wavelength is provided it is interpreted as the wavelength.

>>> import astropy.units as u
>>> import sunpy.net.attrs as a
>>> from sunpy.net import Fido
>>> import sunpy_soar

>>> instrument = a.Instrument("METIS")
>>> time = a.Time("2023-02-01 01:00", "2023-02-01 05:00")
>>> level = a.Level(2)
>>> wavelength = a.Wavelength(121.6 * u.AA)
>>> result = Fido.search(instrument & time & level & wavelength)
>>> result
<sunpy.net.fido_factory.UnifiedResponse object at ...>

For instruments EUI, METIS and SOLOHI passing a range of Wavelength

When a range of wavelength is provided, it is interpreted as the wavemin and wavemax.

>>> wavelength = a.Wavelength(580 * u.AA, 640 * u.AA)
>>> result = Fido.search(instrument & time & level & wavelength)
>>> result
