Scale heights
Hi there, I'm wondering if you've made a mistake in changing the "scale height" in Duna/Param, Laythe/Param, and Jool/Param. This has had the consequence of producing what I believe to be highly invalid atmospheric heights in Template:Infobox/Body, used on all of the celestial body pages, and a table on Science. The formula used there is "ln(1e-6) * -scale_height". Is your change erroneous, or is the formula used to calculate the atmospheric height incorrect? I'm tempted to quickly revert your changes, but hoping you'll spot this message quickly and get a chance to look at it yourself, in case there's good reason for the change. It's not a radius vs. diameter error, is it, or something like that? --Murph (talk) 07:13, 16 May 2015 (UTC)
- Ok, so I've thought a little more on this. Since you didn't give any edit summary, it's impossible for me to know why you changed the numbers for scale height. It seems to me that the number which is most important to average players of the game is the atmosphere height, and that most probably won't care about the scale height. In that regard, the old numbers look like they are more "correct" than the new ones. I don't know about Jool and Laythe, but Duna's atmosphere always started around 41–42km, which matches the old numbers. Accordingly, I'm going to revert your 3 changes to the scale heights, under the assumption that there's some sort of error with them, and that the old numbers are better for now.
- If the problem is actually with the way the wiki's infobox is calculating the atmospheric height, I'd be quite happy to help with any changes needed to the wiki's templates and scripting.
- Here are the numbers for ease of reference, with atmosphere height calculated using the "ln(1e-6) * -scale" formula. Old is before your change. New is what you changed it to.
