Hi,
I'm not sure what you mean WRT to spotread. Doesn't the -V option give
you this sort of functionality ?

Perhaps, rather than create multiple files and have to deal with that,
chartread and
spotread could do the averaging in-memory before writing the final averaged
values to disk?
Unless one is interested in determining the behavior of the instrument, I don't
see the
advantage of hanging on to the intermediate values.
Writing multiple results to disk when being read interleaved would be
complicated and
messy. messy == unreliable code. Even doing averaging in memory means adding a
degree
of elaboration, since currently chartread saves readings directly to the CGATS
object.
Setting an outlier threshold value is not very desirable from a UI point of
view,
since it is yet another parameter that people will wonder how to set.
I think it is possible to make a reasonable attempt to recognize outliers
automatically
using robust mean type function, if a sufficient number of readings is done -
ie. you
can't detect an outlier with less than 3 readings.
