SPS produces a text output file, which is called
'sps_results.dat' unless otherwise specified in the command
file. The results of all tests applied to the data are written to
this file as well as some other relevant information. For checks that
are run over a number of integration periods, results are written to
the logfile or screen output, whilst only the summary is given in the
text file. The final line of the SPS results file consists of the 5
digit run number, a pair of characters and then a group of 10
characters. The pair of characters indicate the run type. The first of
these characters is set to 'u' for a UC bit run or 'y' otherwise. The
second is an 'n' for a neutrino type run and an 'x' otherwise. The
ten following characters are the results of the 10 SPS checks, in the
order given in section (23.2.4). A 'p' indicates that the test
passed, 'f' means it failed, and 'w' is a warning.
