If specified abundances of informative messages are output to stderr. To make
use of this information, you may want to write the standard uvspec output to
one file and the diagnostic messages to another. To do so, try
(./uvspec < uvspec.inp > uvspec.out) >& verbose.txt (depending on your shell you
might need a slightly different syntax). The irradiances
and radiances will be written to uvspec.out while all
diagnostic messages go into verbose.txt. See also quiet.
