Depth of Atmosphere in SJ Query

OK, I need to try and work out what the depth of atmosphere is on
the various sized bodies in SJ.

I'm assuming that the atmosphere stays the same pressure all the
way to the edge of the gravity field, when it suddenly drops to
zero?

This can get more complex if bodies are irregularly shaped, like
a globe with some immense mountains - I'd expect the mountains to
have atmosphere, rather than be sticking out of the gravity field
and hence lack atmosphere.

Maybe I am missing some obvious reference, but the time to get
out of a planet's "gravity well" table on page 51 of CoAS seems
an obvious place to start, which seems to be the irrelevant of
your SR:

Size       Class  Diameter      Time
Fine         A     <10mls       10 rounds (1 turn)
Diminutive   B      10-100mls   2 turns
Tiny         C     100-1Kmls    2 turns
Small        D      1K-4Kmls    3 turns
Medium       E      4K-10kmls   4 turns [Earth-sized]
Large        F     10K-40Kmls   6 turns
Huge         G     40K-100Kmls  12 turns
Gargantuan   H    100K-1Mmls    24 turns (4 hrs)
Colossal     I      1M-10Mmls   48 turns (8 hrs)
Amazing      J     10Mmls+      96 turns (16 hrs)

These are of course the pre-3rdEd one minute rounds and ten
minute turns.

I've said that it takes a SJ ship a little more than 8 minutes to
freefall from the edge of the atmosphere to sea level on an
Earth-like world (Isis, in Maj Space).  Presumably that is at
terminal velocity in one atmosphere pressure all the way.

We did some calculations about a beanstalk to orbit from an
Earth-like world, a while back, and something like 16 miles of
atmosphere seems to stick in my memory.

Thoughts?

Help?
