The mosaic page includes a time-series of JPEGs showing 200-pixel (50") postage stamps, with time increasing from top to bottom. The discovery mosic includes a template observation on the left, discovery image in the middle, and difference image on the right. Subsequent mosaics show a similar collection of images, or the new observation image only, in the case where a subtraction image was not available. The files are generally a few hundred kilobytes. In CTIO mosaics, East is up and North is to the right. For KPNO, East is down and North is to the left.

The finding charts are 3'x3' FITS images centered on the discovery position. The time in the header is the start of the exposure and the world coordinate system in the header is accurate to 0.5". The files are 3 MB. The images are zero-padded to maintain the object in the center even if it was near the edge of the discovery image. Your browser may not bring up saoimage/ximtool automatically on the FITS file. Right-click on the link to save to local disk.

For moving objects, a finding chart is useless, and instead we provide an ASCII list of positions and times.

To make things considerably more exciting, we will color code interesting transients using the following notation
