If it's less than 1 (any Orbit# less than 1.0), then it starts at 0, so it becomes 0 + 0.4 * (Orbit#) in the case of Orbit#0.11 that becomes 0.044 AU.

I was so close!!! I think I can manage it from here now. I have no idea why I could not wrap my head around that. Thank you so much for your help.

That was short lived. When it says HZCO -1.01 to 2.0, is that the the orbit number, such as my first plant is -7 orbits beneath my HCZO, or is it the orbit# as in 0.22, which is only 0.54 less than my HZCO? I keep getting confused on when I should use the orbit slot vs. the actual orbit number. I think it's is a problem of my orbits being so tight combined with zero knowledge of stellar creation, so I have no idea what range I should be expecting. Common sense tells me it should be hot, but unless I am misunderstanding, I just roll on the normal atmosphere table because the "Hot atmosphere" doesn't start until HZCO -1.01. I'm only at -0.54 so it's not considered hot? Then it also say to divide by 10 for an HZCO below 1.0. What am I dividing by 10? The dice result or the orbit#? Neither of those seem to give me a useful result.

I have the same issue with the temperature modifiers. It says if orbit# is less than HZCO-1, then also says to to adhere to divisional differential value translation when HCZO# or Orbit# is less than 1. I know that was probably covered somewhere, but I can't find it. If I assumed that the -1 refers to the orbit# (mine of 0.74) so I just did a straight roll of 5, plus the atmosphere modifier (at the time I thought it was D for +2) which gave me a temp result of 7, or 15 degree. That seemed highly unlikely and which is why I am now questioning my entire atmosphere setup.
"That was short-lived" I laughed so hard at this! This is Me in a nutshell. lol
