Image Format#

Load two-dimensional astronomical images.

Overview#

The Image format is used for loading 2D astronomical imaging data, such as direct images from cameras and imagers.

Usage#

import jdaviz
jdaviz.show()

# Load an image
jdaviz.load('image.fits', format='Image')

Data Requirements#

The data should be a 2D array where:

  • Each pixel represents a spatial position on the sky

  • Pixel values represent flux/intensity measurements

Images can be in various coordinate systems and may include WCS (World Coordinate System) information for relating pixel positions to sky coordinates.

Supported File Formats#

  • FITS files with 2D image data

  • ASDF files with image data

  • JWST imaging data (i2d files)

  • HST imaging data
