The extracted data, called MB3 data set\footnote{Avialble from
\url{http://promisedata.org/repository}.} contains the SILAP scores
and issue counts countas 211 records from seven NASA systems
representing data from 28 different types of
sub-systems (see \fig{types}.
Each record contains the raw
SILAP inputs, listed in \fig{cons} plus the issues found in PITS.
That is, it links the kind of information that might be available early in the lifecycle (SILAP) to
observations made later in the lifecycle (the issue reports).
