This file contains the data from 123 contexts with obsidian availability indices from the Copan valley. The contents for every context are presented in one line, the data file TAB_A10.TXT has 123 lines with 33 variables separated with commas. The 33 variables are, in the following order:
| 1 | Physiographic zone |
| 2 | Sub-community |
| 3 | Group |
| 4 | Site Type |
| 5 | Structure |
| 6 | Operation |
| 7 | Context |
| 8 | Total of all obsidian chipped stone artifacts |
| 9 | Total of obsidian artifacts analyzed |
| 10 | Percentage of artifacts analyzed from the total number of obsidian artifacts |
| 11 | Ixtepeque (N) |
| 12 | Ixtepeque (% from the total of artifacts analyzed) |
| 13 | La Esperanza (N) |
| 14 | La Esperanza (% from the total of artifacts analyzed) |
| 15 | El Chayal (N) |
| 16 | El Chayal (% from the total of artifacts analyzed) |
| 17 | San Martin Jilotepeque (N) |
| 18 | San Martin Jilotepeque (% from the total of artifacts analyzed) |
| 19 | Ucareo (N) |
| 20 | Ucareo (% from the total of artifacts analyzed) |
| 21 | Unidentified source (N) |
| 22 | Unidentified source (% from the total of artifacts analyzed) |
| 23 | Prismatic blades (N) |
| 24 | Prismatic blades (% from the total of artifacts analyzed) |
| 25 | Ixtepeque with cortex (N) |
| 26 | Ixtepeque with cortex (% from the total of Ixtepeque artifacts analyzed) |
| 27 | Excavated volume (m3) |
| 28 | Obsidian density (N/m3) |
| 29 | Obsidian weight (g) |
| 30 | Obsidian density (g/m3) |
| 31 | Ceramic sherds (N) |
| 32 | Obsidian(N)/ceramics Index |
| 33 | Obsidian(g)/ceramics Index |
The first line of the file, for example, looks like this:
"Montanas","","","","","IV/25","secondary context",41,21,51.2,21,100.0,0, 0,0,0,0,0,0,0,0,0,7,33.3,2,9.5,"","",31.7,"","","",""
It belongs to the first context analyzed, which indicates the physiographic zone "Montanas"; there is no subcommunity, nor group, site type or structure. The operation is "IV/25" and it belongs to the context "secondary context". This context has a total of 41 obsidian artifacts, 21 artifacts (51.2%) were analyzed. Then obsidian artifacts are presented according to their sources: Ixtepeque, 21 artifacts (100.0% of the obsidian analyzed); La Esperanza, 0 (0%); El Chayal, 0 (0%); San Martin Jilotepeque, 0 (0%); Ucareo, 0 (0%); unidentified sources, 0 (0%). The line continues with the total of prismatic blades from the context, 7 blades (33.3%); Ixtepeque with cortex, 2 artifacts (9.5% of the total of Ixtepeque artifacts); excavated volume, 0; obsidian density (artifacts per cubic meter), 0; obsidian weight, 31.7 grs; obsidian density (g per cubic meter), 0; ceramic sherds, 0; obsidian number / ceramics ratio: 0.0, obsidian weight / ceramics ratio: 0.0. 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","44/3","midden",114,112, 98.2,110,98.2,0,0,0,0,0,0,2,1.8,0,0,71,63.4,0,0,3.4,32.9,431.3,126.9,"","",""
This indicates the physiographic zone "Vega", subcommunity "Principal Group", group 10L-1, site type: 5, structure: 10L-22A. It belongs to the operation "44/3" and the context "midden". This context has a total of 114 obsidian artifacts, 112 artifacts (98.2%) were analyzed. Then obsidian artifacts are presented according to their sources: Ixtepeque, 110 artifacts (98.2% of the obsidian analyzed); La Esperanza, 0 (0%); El Chayal, 0 (0%); San Martin Jilotepeque, 0 (0%); Ucareo, 2 (1.8%); unidentified sources, 0 (0%). The line continues with the total of prismatic blades from the context, 71 blades (63.4%); Ixtepeque with cortex, 0 artifacts (0% of the total of Ixtepeque artifacts); excavated volume, 3.4m3; obsidian density (artifacts per cubic meter), 32.9; obsidian weight, 431.3 grs; obsidian density (g per cubic meter), 126.9; ceramic sherds, 0; obsidian number / ceramics ratio: 0.0, obsidian weight / ceramics ratio: 0.0. The quotation marks around "Vega" and "Principal Group" indicate that these variables are alphanumeric and "" indicates the absence of data.
