The image above is the CFHTLS D1 field. You can zoom in and out and
scroll around the image the using your mouse and the controls much
like Google Maps. Click on the buttons on the right hand
side to view the field at different wavelengths.
You can also get a science image in FITS format (for the CFHTLS images only).
Pan and zoom to the position and resolution you want, pick the filter, then click on
the "Get FITS image" button.
The non-CFHTLS images were produced by taking publicly available images (the
list of data sources is here) and
resampling them to the scale of the CFHTLS images. In some cases,
this causes the images to be drastically over-sampled (the Spitzer MIPS
data, for example) or under-sampled (the HST images). The colour images for
the CFHTLS data are produced from the gri images.
