The images from TAD Telescope, Tenerife.

There are 100 fits files in the archive, including exposures in different
filters, as well as flat and dark frames. Detailed description is
included in the 'tad_images.list' file:  you can see, to
each image, what filter is, the exptime and if a bias, a flat, a dark or a
"Light frame", what is the way that the software calls the normal images.
The filters you can make the images are "blue", "red", "green", "Lunar", and
without any filter, called "clear".
