A JPEG representation of the image is displayed on this page. North is up; East is to the left. A non-linear transformation of pixel values to grayscales was used to make the JPEG image; due to the large dynamic range of the data this JPEG image does not display both faint and bright emission well. This JPEG image is not suitable for quantitative analysis; download the FITS image file for this purpose.
