Details for values of line 5 through N+5

"relX" and "relY" are the pixel coordinates of the MODIS swath data, relative to the subset of MODIS data overlapping the ASTER image such that (0,0) is the upper left MODIS pixel for the ovelappying area

"X" and "Y" are the pixel coordinates in MODIS swath image (listed on line 3), with upper left corner pixel (0, 0)
X = along scan direction
Y = along track direction

"lat" and "lon" are latitude and longitude in decimal degrees 
(Southern latitude is negative, Eastern longitude is positive)

"MODIS" is the MODIS fire classification (more information is at http://edcdaac.usgs.gov/modis/mod14therm.html)
0: not processed (missing input data)
2: not processed (other reseason)
3: water mask (no fire algorithm applied)
4: cloudy (significantly obscured by clouds so that no attempt is made to extract fire information)
5: no fire
6: unknown (information from adjacent pixel is unknow and contectual classifier can not be applied and single pixel information is not conclusive)
7: low-confidence fire 
8: nominal-confidence fire 
9: high-confidence fire


"count" is the number of ASTER fire pixels within corresponding MODIS pixel
"Moran" is the Moran's I calculation for the ASTER fire data within the corresponding MODIS pixel
"variance" is the variance of ASTER fire data within corresponding MODIS pixel
