CarpetIOScalar is for outputting reduction results; this does not really apply to scalar variables. You can output scalar variables without reduction using CarpetIOASCII; this is called "0D" output there since scalars are 0-dimensional grid variables (this is also how they are implemented internally).
out0D_vars = "..." out0D_every = ...
You can also use 0D output to output multi-dimensional grid variables at a certain point, e.g. the origin.

Hi all. This seems trivial, but ... How do I avoid reductions (average, minimum, maximum, etc) for scalar output of a SCALAR variable in CarpetIOScalar? CactusBase/IOBasic recognises the SCALAR type of the variable, and doesn't bother with reduction. Carpet/CarpetIOScalar seems to ignore the type, and does the reductions. At least, it outputs several files with trivial information in them. I can force it to only generate one file by setting outscalar_reductions ="average" (for instance), but then I lose the reductions for all other (non-SCALAR) variables.
