**From pp 168 Atmosphere:**

The Atmosphere tables on this page have a range ofThe Atmosphere characteristic measures the type of atmosphere present, and is determined by rolling 2d6-7 andadding the planet's Size. Under most circumstances, a planet cannot have an Atmosphere score greater than twice its Size.

**0 to +12**

O.K. so no problem, roll 2 D6 and subtract 7, giving a possible range of -5 to +5 before modifying this value using the planet's size previously rolled, which uses 2D6-2 (0 to +10 range)

Hypothetical roll 1:

----------------------

Size: (4+5)-2=7

Atmo: ((6+5)-7)+7=

**11**

Hypothetical roll 2:

-----------------------

Size: (6+5)-2=9

Atmo: ((6+6)-7)+9=

**14**

Hypothetical roll 3:

-----------------------

Size: (1+1)-2=0

Atmo: ((1+1)-7)+0=

**-5**

Both rolls #2 and #3 above are well out of the range provided on the Atmo tables, and I might assume that one could round-up or down here to 12 and 0 respectively, but I hate to assume when other tables that can generate values out of range clearly state "12+" or "2 or less" when this condition can occur.

Any guidance is appreciated.
