Cavalerius

D=59 km
Center: 5.1°N, 293°E

Floor Area = 492 km^2
Observed Density (@ 1km): 3000 ± 2500
Simone's Age: 2.1 ± 0.3
Stoffler epoch: Eratosthenian
Fit Density (@ 1km): 2700 ± 400
PF fit: OK - limited data, small number statistics, large error


Age Calculation Notes: 
OK fit, but few data points and errors are large. Used Melosh gravity.

USGS geology: 
Eratosthenian

Wilhelms: 
Eratosthenian

Floor material: 
Deep crater, but small, eroded peak. Mostly smooth - a few small hummocks. Ejecta on top of mare. Likely original.

Geology Observations: 
Ejecta blanket somewhat visible, especially on mare. Rim still sharp. Small central peak - more like a cluster, and it appears eroded. No evident collapses. One 500 m secondary identified - part of cluster(?). Formed at boundary of Oriental ejecta and mare. Surrounded by filled craters.

SFD Observations: 
Dominated classes 2 and 4. Kind of flat distribution. Slope(Diff)=-1.3 ± 0.9 

Also examined by Baldwin (1985)
Baldwin: density = 5700 ± 580, age = 3.4 ± 0.2 Ga (area = 790 km^2, likely ejecta)
