Habitability Range Chart When trying to exchange information with other players about planets in your/their vicinity, it's helpful to be able to get a feel for where the planet's going to sit as far as habitability for your race, or for theirs. I jotted down some figures on how to translate values in the display to "relative difference" figures. This allows you to figure just how far you would have to terraform a particular planet to either make it perfect, or at least make it habitable :) There are a total of 101 points in each of the three spectra involved. This allows for a "center point", plus 50 points to either side. Temp and Radiation are pretty straight forward as far as translations go, but gravity was a little tricky until I thought about it for a few minutes. The formula for Gravity moving UP from the center point is: Move up in units of 0.04 G for the first 25 points, then move up in units of 0.24 G for the remaining 25 points. In order to get the values for the points BELOW center (centerline is 1.00 G), you divide the number 1 by the equivalent upper point. So ten points above center would be 1.40 G, and ten points below center is then shown as (1/1.40) = 0.71 G. Temp moves in units of 4 degrees C per point, from -200 C to 200 C. Radiation is the simplest, moving in units of 1, ranging from 0 to 100. In order to keep the gravity units straight, I sketched out a little chart, showing the values of all three based off of "point position". I'm including it here, in case anyone else wants to use it. This can give you a feel for how close a planet is to your range, when you know only the existing values, and haven't scanned the planet yourself. What I'd *REALLY* like is a way to translate these relative offsets, along with the racial ranges, into the true percentage value of a planet. Is there anyone out there ambitious enough to work out the formula? Or perhaps, if we all plead with Jeff & Jeff, the'd just TELL US what the formula is.... And the formula for how to compute the Advantage point costs of the different ranges would be great, too.... ;-) Use the "Radiation" column as the index column, if you like. ----------- cut ---------------------- Stars v2.0a Habitability Range Chart g C mR Grav-Temp-Rad 0.12 -200 0 0.12 -196 1 0.13 -192 2 0.13 -188 3 0.14 -184 4 0.14 -180 5 0.15 -176 6 0.15 -172 7 0.16 -168 8 0.17 -164 9 0.17 -160 10 0.18 -156 11 0.19 -152 12 0.20 -148 13 0.21 -144 14 0.22 -140 15 0.24 -136 16 0.25 -132 17 0.27 -128 18 <--- default Radiation lower end for custom races 0.29 -124 19 <--- default Grav/Temp lower end for custom races 0.31 -120 20 0.33 -116 21 0.36 -112 22 0.40 -108 23 0.44 -104 24 0.50 -100 25 0.51 -96 26 0.52 -92 27 0.53 -88 28 0.54 -84 29 0.55 -80 30 0.56 -76 31 0.58 -72 32 0.59 -68 33 0.60 -64 34 0.62 -60 35 0.64 -56 36 0.65 -52 37 0.67 -48 38 0.69 -44 39 0.71 -40 40 0.73 -36 41 0.75 -32 42 0.78 -28 43 0.80 -24 44 0.83 -20 45 0.86 -16 46 0.89 -12 47 0.92 -8 48 0.96 -4 49 1.00 0 50 <---- centerline 1.04 4 51 1.08 8 52 1.12 12 53 1.16 16 54 1.20 20 55 1.24 24 56 1.28 28 57 1.32 32 58 1.36 36 59 1.40 40 60 1.44 44 61 1.48 48 62 1.52 52 63 1.56 56 64 1.60 60 65 1.64 64 66 1.68 68 67 1.72 72 68 1.76 76 69 1.80 80 70 1.84 84 71 1.88 88 72 1.92 92 73 1.96 96 74 2.00 100 75 2.24 104 76 2.48 108 77 2.72 112 78 2.96 116 79 3.20 120 80 3.44 124 81 <---- default Grav/Temp upper end for custom races 3.68 128 82 <---- default Radiation upper end for custom races 3.92 132 83 4.16 136 84 4.40 140 85 4.64 144 86 4.88 148 87 5.12 152 88 5.36 156 89 5.60 160 90 5.84 164 91 6.08 168 92 6.32 172 93 6.56 176 94 6.80 180 95 7.04 184 96 7.28 188 97 7.52 192 98 7.76 196 99 8.00 200 100 By Barry Kearns Other Stars! cheats hints faqs solutions: 1.
