SunPy instr¶
The instr submodule contains instrument specific routines, generally this
submodule is focused on routines that process calibrated data.
sunpy.instr Package¶
This is where libraries for individual missions resides
sunpy.instr.aia Module¶
Provides processing routines for data captured with the AIA instrument on SDO.
sunpy.instr.fermi Module¶

get_detector_sun_angles_for_time(time, file) |
get the GBM detector angles vs the sun for a single time. |
get_detector_sun_angles_for_date(date, file) |

plot_detector_sun_angles(angles) |
Plots the Fermi/GBM detector angles as a function of time. |
met_to_utc(timeinsec) |
Converts Fermi Mission Elapsed Time (MET) in seconds to a datetime object. |
sunpy.instr.goes Module¶
Contains functions useful for analysing GOES/XRS data.
Each of the Geostationary Operational Environmental Satellite (GOES) series since the mid-1970s has carried an X-Ray Sensor (XRS) which observes full-disk-integrated solar flux in two broadband channels: 1–8 angstrom (long); and 0.5–4 angstrom (short). For more information on the GOES/XRS instrument, see [Ref1]. GOES/XRS has become the “standard candle” for solar coronal observations due its longevity and consistency. The GOES event list, based on GOES/XRS observations, has become the standard solar flare catalogue. See https://www.ngdc.noaa.gov/stp/solar/solarflares.html for information on the GOES event list definitions and data.
The functions in this module provide useful software to analyse GOES/XRS
observations. First they allow the GOES event list to be imported into a
Python session (get_goes_event_list).
They also allow the thermodynamic properties of the emitting solar plasma to be
determined. Temperature and emission measure are obtained using
calculate_temperature_em, this function currently relies on
lookup tables relating the GOES fluxes to the isothermal temperature and volume
emission measure. These tables were calculated by functions in SolarSoftWare
(SSW) using the CHIANTI atomic physics database ([Ref2]). For more detail, see
the docstring of calculate_temperature_em` and references therein.
The radiative loss rate of the soft X-ray-emitting plasma across all
wavelengths can be found with
calculate_radiative_loss_rate, which makes use of a look up
table calculated by functions in SSW using CHIANTI. This table relates the
temperature and emission measure of the emitting solar plasma to the thermal
energy radiated over all wavelengths. For more information on how this is
done, see the docstring of _calc_rad_loss and reference
therein.
Meanwhile, the X-ray luminosity in the two GOES passbands can be obtained by
calculate_xray_luminosity. To do so, this function calls
_goes_lx and calc_xraylum.
