And so the madness continues. This change replaces

     ts = MINVAL(ts_array, MASK=(ABS(ts_array - 0.02_wp) < 0.001_wp))

by

     ts = MINVAL(ts_array, MASK=(ABS(ts_array - 0.02_wp) < 0.00001_wp))

This would appear to make the MASK condition less likely to be met, and therefore run the risks mentioned in #600, but there we go.

This change also outputs some unobjectionable diagnostics - in the case of the RS test it says

... (from ropp_pp_preprocess_grasrs):  Detecting raw sampling data at   1000.0 Hz

No other impact on the test, as that dataset does not include OL data (as the diagnostics above show).

Committed change at r6844.

No documentation changes needed.

Closing ticket.
