The header files for avg.log and std_dev.log are identical. The file data
may be linked by *run*, *year*, and *index* number. All
metrics are for a single year; they are not cumulative.

Contents of avg.log and std_dev.log:

**run**: a run consists of a single set of coefficient
values and is executed MONTE_CARLO_ITERATIONS number of times from start to stop year

**year**: the representative date for a growth
cycle

**index**: control year number

**sng**: the number of new urban pixels generated from spontaneous growth

**sdg**: the number of new urban pixels generated from new spreading center growth

**sdc**: relic data type no longer used

**og**: the number of new urban pixels generated from edge growth

**rt**: the number of new urban pixels generated from road influenced growth

**pop**: the total number of urban pixels

**area**: the total number of urban pixels (same as *pop*)

**edges**: the total number of urban/non-urban pixel
edges

**clusters**: the total number of urban clusters

**xmean**: the average urban pixel column value

**ymean**: the average urban pixel column value

**rad**: the radius of the circle which encloses the
urban area: (pow ((area / pi), 0.5))

**slope**: average slope of urbanized cells

**cl_size**: average urban cluster size

**diffus**: dispersion_coefficient value

**spread**: spread_coefficient value

**breed**: breed_coefficient value

**slp_res**: slope_coefficient value

**rd_grav**: road_gravity_coefficient value

**%urban**: Percent of the number of urban pixels
divided by the total number of pixels in the study area (nrows*ncols)
minus the number of pixels that are completely excluded from urban growth:
((100.0 * urbancount) / (total_pixels - (noncount+road pixels))

**%road**: Percent of the number of road pixels divided
by the total number of pixels in the study area (nrows*ncols) minus the
number of pixels that are completely excluded from urban growth: ((100.0
* roadcount) / (total_pixels - noncount))

**grw_rate**: Percent of the new urban pixels in one
year divided by the total number of urban pixels: (100 * num_growth_pix
/ pop)

**leesalee**: a shape index, a measurement of spatial
fit between the model's growth and the known urban extent for the control
years. In predict mode
this value will always be zero (0):

where A is modeled and B is actual urban area.

**grw_pix**: total number of new urban pixels
