Fabricius

D=79 km
Center: 43°S, 42°E

Floor Area = 792 km^2
Observed Density (@ 1km): 4500 ± 2300
Simone's Age: 2.2 ± 0.3 (+sec: 3.3)
Stoffler epoch: Eratosthenian
Fit Density (@ 1km): 2800 ± 400
PF fit: OK


Age Calculation Notes: 
Fit is decent. Error bars are a little large. Middle bins falls somewhat above the MPF. Used Melosh gravity.

USGS geology: 
Imbrian

Wilhelms: 
Eratosthenian

Floor material: 
Deep crater, but small peak. Hummocky and some cracks on smoother areas. Likely original.

Geology Observations: 
Ejecta blanket visible, but has a little erosion. Rim looks slightly eroded. Small central peak. Large collapse on north side of crater, may be caused by formation on a larger, older crater. A few secondary chains/clusters identified. All under 1 km. Formed on highlands, perhaps on Nectaris ejecta. Surrounded by filled craters.

SFD Observations: 
Flat shape. Dominated by classes 1 (large) and 4 (small). Slope(Diff)=-3.2 ± 0.2
Secondaries shape similar within error. Slope not calculated - only two points.
