[MSNoise] Mismatch between the dates of the 005/010_day stacks and the daily stacks?

[Thomas Lecocq]

Dimitris,

What you've notice is linked to the fact that, even if 1 day is missing, 
the 5-day stack will export the existing 4 days. Same for the last day 
of 2013, as this one exists, when the stack procedure sees the existing 
31/12, then the 5-day stacking for 4/1 (which is  [31/12, 1/1, 2/1, 3/1, 
4/1]) doesn't fail because at least some data is there.

I admit, this is not clear in the documentation !
