Maybe Caltech is no more what Caltech was supposed
to be (so excellent) ?
As a Caltech alumnus -- I get their fund-raising requests all too
regularly. Their new motto is "There's only one -- Caltech." I must not
be the only person who mentally appends either "thankfully" or "and one
is more than enough."
The percentages reported in the survey are not very useful. With some
effort, I was able to find the following statistics of Rietveld
software (some time ago when there were only 145 respondents.) This is
what I found interesting:
Of the 145 people who responded, 140 used at least one Rietveld program.
Of the 140:
75% of those people used GSAS.
40% used FULLPROF
the next highest on the list was used by ~15%
By memory, the proportions of European vs US vs "other" respondents
were ~ equal.
It would be interesting to correlate software preference against most
commonly used data types (TOF vs CW neutron, lab vs synchrotron, etc.).
I tend to think that FULLPROF is the clear favorite of the magnetic
scattering community, but I have no data to prove that.
