for a weekly data set, the accessor $obsmicro returns the day instead of
the week. I would have expected that for this frequency the
"micro"-frequency should refer to the calendar week. See here:
open nysewk.gdt -q
series obsmin = $obsminor
series obsmic = $obsmicro # referece to day instead of week
print close obsmin obsmic -o
This is with latest git on ubuntu.
