Hello,

To run the USNO A2 from hard disk, you have to open the guide.dat file
in the root directory and insert the following line :

A2_PATH=x;dir
where 'x' is the threshold magnitude from which stars of the usno appear
and 'dir' is the path of the directory of the usno files (with an \ at
the end)
