Moin,
I'm bunching a few mails together, to not clutter the mailinglist too much

I made a revised figure with a few improvements:
- the PSDs now cross at 1Hz
- the theoretical ADEV/MDEV pre-factors are now explicitly stated

When we say ADEV does not distinguish those, we mean that the slope of

Hi, Magnus!
Thank you for this! I am of course nowhere near really comprehending it
from reading it a couple of times, but I will still show my ignorance by
asking a couple of questions with respect to the power law noise table.
Counting on your day being still non-grumpy.. :D

Hi, Tom!
I have looked at the pages you link to many times, they really are very
good - my goal here was to get down to the nitty-gritty myself, just
understand the details better.
Regarding possible bias in the Excel RNG, this was my first hunch as well,
but when I repeated the experiment with

Hi Ole,
I saw this post and thread, but waited until I had the time to address
it sufficiently, as it is an important topic. As such, I really enjoy
you asking the question as I am sure it will be a relevant question for
many more on this list.

FWIW the python "colorednoise" (aka. Kasdin-Walter) repo has a figure:

For this you should expect 1.73 which is sqrt(3). For example:
C:\tvb> rand1 100 | adev4 /a 1
rand1 100(count) 1(sdev) 0(mean) 1540577979(seed)
** tau from 1 to 1 step 1

You are correct, my statement was imprecise - I generate numbers
