Finsen

D=73 km
Center: 42°S, 182°E

Count Area: 583 km^2
Observed Density (@ 1km): 4500 ± 2800
Age: 3.5 ± 0.1
Stoffler epoch: Late Imbrian
Fit Density (@ 1 km): 4900 ± 500
PF fit: OK

Age calculation notes:
Match between data and MPF is good, however number of points is minimal. Used Melosh gravity scaling.

USGS geology: 
Eratosthenian

Wilhelms: 
Eratosthenian

Floor material: 
Peak is large and sharp, and crater is deep. Most of the floor is smooth, there is some hummocks in the north. Surrounded by many craters that appear to be filled with mare. Tendency is towards being original.

Geology Observations: 
Ejecta blanket and some secondaries visible, but no rays observed in WAC. Perhaps a collapse on the north wall, (avoided) possibly caused by formation on rim of older, larger crater. A couple secondary clusters/chains observed, but still small (< 800 km). 

SFD Observations: 
Steep slope. Dominated by classes 3 & 4 for small craters and 1& 2 for larger. Classes have similar shape to "all". Slope(Diff)=-4.5 ± 0.4
Secondaries have similar shape. Slope not computed - only two points.
