Optical Transient Detector data is processed and archived by day. The browse products are GIF images giving a graphical representation of the OTD data for each day. To get a small preview image of one month of OTD browse products, select [Thumbnails] option corresponding to the month and year you are interested in. If you have a slow connection or already know which day or days you want, and do not want the preview images, select the [text] option instead, and you will get a text-only calendar of that month.
