3D Spectrum Format#

Load three-dimensional spectroscopic data cubes.

Overview#

The 3D Spectrum format is used for loading spectroscopic data cubes where flux varies along three dimensions - typically two spatial dimensions and one spectral dimension.

Usage#

import jdaviz
jdaviz.show()

# Load a 3D spectrum cube
jdaviz.load('cube.fits', format='3D Spectrum')

Data Requirements#

The data should be a 3D array where:

  • Two axes represent spatial dimensions (X, Y positions on sky)

  • One axis represents the spectral dimension (wavelength/frequency)

  • Pixel values represent flux measurements

This format is commonly used for Integral Field Unit (IFU) spectroscopy data.

Supported File Formats#

  • FITS files with 3D data cubes

  • JWST MIRI and NIRSpec IFU data (s3d files)

  • Other IFU instrument data cubes
