This file contains the data from 123 contexts with obsidian artifacts from the Copan valley, Late Classic period. The contents for every context are presented in one line, the data file TAB_A09.TXT as 123 lines with 34 variables separated with commas. The 34 variables are, in the following order:
| 1 | Physiographic zone |
| 2 | Sub-Community |
| 3 | Group |
| 4 | Site type |
| 5 | Structure |
| 6 | Operation |
| 7 | Prismatic blades (N) |
| 8 | Prismatic blades (%) |
| 9 | Macroblades (N) |
| 10 | Macroblades (%) |
| 11 | Polyhedral cores (N) |
| 12 | Polyhedral cores (%) |
| 13 | Prismatic blade points (N) |
| 14 | Prismatic blade points (%) |
| 15 | Bifacial points (N) |
| 16 | Bifacial points (%) |
| 17 | Bifacial thinning flakes (N) |
| 18 | Bifacial thinning flakes (%) |
| 19 | General debitage (N) |
| 20 | General debitage (%) |
| 21 | Scrapers (N) |
| 22 | Scrapers (%) |
| 23 | Notched flakes (N) |
| 24 | Notched flakes (%) |
| 25 | Denticulates (N) |
| 26 | Denticulates (%) |
| 27 | Drills (N) |
| 28 | Drills (%) |
| 29 | Flake cores (N) |
| 30 | Flake cores (%) |
| 31 | Eccentrics (N) |
| 32 | Eccentrics (%) |
| 33 | Total (N) |
| 34 | Total (%) |
The first line of the file, for example, looks like this:
"Montanas","","","","","IV/25",7,33.3,0,0,0,0,0,0,0,0,0,0,14, 66.7,0,0,0,0,0,0,0,0,0,0,0,0,21,100
The first context analyzed belongs to the physiographic zone "Montanas", there is no subcommunity, nor group, site type or structure. It belongs to the operation "IV/25". There are 7 prismatic blades (33.3%), 0 macroblades (0%), 0 polyhedral cores (0%), 0 prismatic blade points (0%), 0 bifacial points (0%), 0 bifacial thinning flakes (0%), 14 general debitage (66.7%), 0 scrapers (0%), 0 notched flakes (0%), 0 denticulates (0%), 0 drills (0%), 0 flake cores (0%) and 0 eccentrics (0%), with a total of 21 artifacts (100.0%). The quotation marks around "Montanas" and "IV/25" indicate that these variables are alphanumeric and "" indicates the absence of data.
The last (123th) line is:
"Vega","Principal Group","10L-1","5","10L-22A","41/3",71,63.4,2,1.8, 3,2.7,0,0,20,17.9,0,0,12,10.7,2,1.8,0,0,2,1.8,0,0,0,0,0,0,112,100
This indicates the physiographic zone "Vega", subcommunity "Principal Group", group "10L-1", site type "5", structure "10L-22A", operation "41/3". There are 71 prismatic blades (63.4%), 2 macroblades (1.8%), 3 polyhedral cores (2.7%), 0 prismatic blade points (0%), 20 bifacial points (17.9%), 0 bifacial thinning flakes (0%), 12 general debitage (10.7%), 2 scrapers (1.8%), 0 notched flakes (0%), 2 denticulates (1.8%), 0 drills (0%), 0 flake cores (0%) and 0 eccentrics (0%), with a total of 112 artifacts (100.0%). The quotation marks around "Vega" and "Principal Group" indicate that these variables are alphanumeric and "" indicates the absence of data.
