10  Percentage of bifaces (among all artifacts) 
11  Error range at the 80% confidence level 
12  Error range at the 95% confidence level 
13  Error range at the 99% confidence level 
14  Mean retouch debris density (per square meter) 
15  Error range at the 80% confidence level 
16  Error range at the 95% confidence level 
17  Error range at the 99% confidence level 
18  Retouch debris to utilized bifaces ratio 
19  Error range at the 80% confidence level 
20  Error range at the 95% confidence level 
21  Error range at the 99% confidence level 
22  Mean basalt artifact density (per square meter)
