The orange data comes from ALMA’s low-resolution Band 3 test observations. The white boxes outline where ALMA Band 6 early test data (amber) were taken. Inside are also the areas where ALMA Band 7 science verification data (yellow) were taken. During Early Science observations, ALMA will fill in more of the millimeter/submillimeter picture of the Antennae Galaxies.
For technical information about the Band 7 science verification data, please visit the ALMA Science Verification website.
