Moon Hotspot

A few points of data:
-13, -168, 64%
-15, -169, 65%
-16, -170, 66%

Using these points I formed a line under that assumption that 1%=1 deg (which I know is incorrect), and adjusted:

-40, 166, 85%
-44, 170, 83%
-46, 160, 87%

getting better, but still a ways to go. For future points, I would continue along this path until the effectiveness drops, then drop a perpendicular to the northwest at an appropriate point.

Next Suggested Points:
-53, 153
-60, 146

thanks for these Bdiah. using them, i got 98% with -35,140 and then the full 100% with -37,140. screencap to follow !

I recall that there has been a fair amount of discussion but have we ever determined the actual equation modeling how effectiveness falls off with respect to distance?

zakharov's algorithm is developed over these posts:

and concludes with:

[QUOTE]
eff(hs,p) = 100 - 125*d(hs,p)/pi

where pt is any point, hs is the hotspot and d is the great circle distance function with radius = 1.

The algorithm is like this:

for every point p with integer coordinates on the map
-assume p is the hotspot
-calculate the efficiency of all known datapoints and count how many match the points that match every datapoint are hotspot candidates.

[/QUOTE]

that won't get you right to the 100% solution, as there are a couple more wrinkles (including floating pt calcs), but if you get close, feel free to query at that time.

Just wanted to say [b]thanks[/b] for this thread!

Just moved my base for the first time and got 99%.

[Grumpdogg]

Thanks heaps for the coordinates again everyone.

[Emphix]

First timer here Thank you for the hotspot, 100% indeed!

[Magister Agricolarum]

(-2.10890, 179.29688) gives 83% (for January). (44.59047, 146.95313) only gives 51%.

[Haflinger]

(0, 160) = 83%
(10, 170) = 77%
(-10, 150) = 85%

[hilowe]

(-13, -169) = 83%

[thebly]

-10,120 = 67
-8,133=75
-7,146 = 82

[Velocity111]

-37, 140 = 80%

[Emphix]

10, -30 is 50%
-37, 140 is 80%
-60, -170 is 71%
-1, 150 is 81%

-15, 155 =89%
-15, 160 =92%
-36, 141 =81%

I would suggest someone try -20, 165 next

97%

-21, 165 and -24, 165 are also 97%.

Excellent tip!

Location: -20.26094, 165.72937 = 97%

[Provost Zakharov]

Happy new year everyone.

EDIT: here's a cool plot that shows all the datapoints for this month's calculation: each ring is one datapoint, and the red dot at their intersection is the hotspot.

That's pretty awesome provost!

thanks Provost - excellent work as always !

Nearly forgot about this with the holidays and all, thanks as always

Nice! What are you using to make this?

[NuclearTrogo]

Wonder if there's a 0% effectiveness somewhere...

It's made with Mathematica, same thing with the graphics earlier in this thread ([url="http://forums.cybernations.net/index.php?showtopic=64843&view=findpost&p=1879161"]here[/url],[url="http://forums.cybernations.net/index.php?showtopic=64843&view=findpost&p=1879493"]here[/url],[url="http://forums.cybernations.net/index.php?showtopic=64843&view=findpost&p=1885515"]here[/url]). Mathematica rocks

The efficiency is clamped above 50%. That's good for lazy players, but it actually makes the hotspot harder to find because any datapoints inside the 50% zone don't give much useful information.

[Chintan]

I've got this awesomeness ready to find the hotspot this Monday:
BTW, if anyone has the exact formula for finding the efficiency that gets the floating point error correct, please send it to me, because the formula I'm using now is slightly off.

[size="5"][b]Possible Moon Hotspot Locations (December 2010):[/b][/size]

Tried a location? Post the result in this thread! Every point helps, even if it gives 50%.

Points Tried so far (lat, long):
(-13, -168): 64%
(-40, 166): 85%

Priority Points (try these next):
lon=141&lat=-34
lon=168&lat=-61

(If you decide to try a priority point, post here that you're trying it, try it, and post the result, so that someone else doesn't try the same point)
