1D Spectrum Format#

Load individual one-dimensional spectra.

Overview#

The 1D Spectrum format is used for loading single spectroscopic observations where the data varies along one dimension (typically wavelength or frequency).

Usage#

import jdaviz
jdaviz.show()

# Load a 1D spectrum
jdaviz.load('spectrum.fits', format='1D Spectrum')

Data Requirements#

The data should contain:

  • Spectral axis: Wavelength, frequency, or energy values

  • Flux: The measured intensity at each spectral point

  • Uncertainty (optional): Error or uncertainty values

Supported File Formats#

  • FITS files with spectral data

  • ASDF files

  • ECSV files with spectral columns

The loader automatically detects and parses standard spectroscopic data formats.

UI Access#
