# SunPy spectra¶

## Overview¶

One of core classes in SunPy is a Spectrum and Spectrogram. These representing a spectrum as a specific point in time or one as a function of time, respectively. Individual instruments are supported through subclasses. To see what instrument are supported see Spectrum Classes and Spectrogram Classes.

## sunpy.spectra.spectrum Module¶

### Classes¶

 Spectrum(data, freq_axis) Class representing a 1 dimensional spectrum.

None yet.

## sunpy.spectra.spectrogram Module¶

Classes for spectral analysis.

### Classes¶

 Spectrogram(data, time_axis, freq_axis, …) Spectrogram Class. LinearTimeSpectrogram(data, time_axis, …) Spectrogram evenly sampled in time.

## Spectrogram Classes¶

There are a series of subclasses which are specialised for each instrument.

## sunpy.spectra.sources Package¶

Datasource-specific classes

This is where datasource specific logic is implemented. Each mission should have its own file with one or more classes defined.

### Classes¶

 CallistoSpectrogram(data, time_axis, …[, …]) Classed used for dynamic spectra coming from the Callisto network. SWavesSpectrogram(data, time_axis, …)
