This file contains the data from 13 contexts with lithic artifacts from the Copan valley. The contents for every context are presented in one line, the data file TAB_A04.TXT has 13 lines, with 52 variables separated with commas. The 52 variables are, in the following order:
 
 

The first line of the file, for example, looks like this:

"Vega","El Bosque","","","IV/99","31,32,36,37","midden",33,31,93,1,1,2,1,1,2,1,1,2,0,0,0,0,0,0,0,0,0,0,0,0,14,11,17,0,0,0,50,45,116,17,5,6,1,1,1,18,6,7,68,52,123

The first context analyzed belong to the physiographic zone "Vega", subcommunity "El Bosque", there is no group, nor number of structure, platform or plaza. It belongs to the operation "IV/99", lot numbers "31,32, 36, 37" and the context is a "midden". Then we have the numbers of obsidian and chert artifacts analyzed. There are 33 obsidian prismatic obsidian blades; 31 present use-wear, with a total of 93 independent use zones (IUZ). There is 1 obsidian macroblade; 1 presents use-wear, with a total of 2 independent use zones (IUZ). There is 1 obsidian macroflake; 1 presents use-wear, with a total of 2 independent use zones (IUZ). There is 1 obsidian small percussion blade; 1 presents use-wear, with a total of 2 independent use zones (IUZ). There are 0 obsidian polyhedral core fragments; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian bifacial points; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian prismatic blade points; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian bifacial thinning flakes; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 14 obsidian flakes; 11 present use-wear, with a total of 17 independent use zones (IUZ). There are 0 obsidian denticulates; 0 presents use-wear, with a total of 0 independent use zones (IUZ). Subtotal of obsidian artifacts analyzed = 50. Subtotal of obsidan with use-wear = 45. Subtotal of independent use zones (IUZ) in obsidian artifacts = 116. There are 17 chert flakes; 5 present use-wear, with a total of 6 independent use zones (IUZ). There is 1 chert scraper; 1 presents use-wear, with a total of 1 utilization zone (IUZ). Subtotal of chert artifacts analyzed = 18, Subtotal of chert artifacts with use-wear= 6. Subtotal of independent use zones (IUZ) in the chert artifacts = 7. Total of lithic artifacts analyzed: 68. Total of lithic artifacts with use-wear: 52. Total of independent use zones (IUZ): 123. The quotation marks around "Vega" and "El Bosque" indicate that these variables are alphanumeric and "" indicates the absence of data.

The last (13th) line is:

"Vega","Principal Group",10L-3,"Great Plaza","V/63/7","","midden",33,31,83,0,0,0,3,3,7,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,3,3,4,0,0,0,39,37,93,1,0,0,0,0,0,1,0,0,40,37,93

Which indicates the physiographic zone "Vega", subcommunity "Principal Group", group "10L-3", structure "Great Plaza". It belongs to the operation "V/63/7", there is no lot number and the context is a "midden". Then we have the numbers of obsidian and chert artifacts analyzed. There are 33 obsidian prismatic obsidian blades; 31 present use-wear, with a total of 83 independent use zones (IUZ). There are 0 obsidian macroblades; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 3 obsidian macroflake; 3 present use-wear, with a total of 7 independent use zones (IUZ). There are 0 obsidian small percussion blades; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian polyhedral core fragments; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian bifacial points; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian prismatic blade points; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 0 obsidian bifacial thinning flakes; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 3 obsidian flakes; 3 present use-wear, with a total of 4 independent use zones (IUZ). There are 0 obsidian denticulates; 0 presents use-wear, with a total of 0 independent use zones (IUZ). Subtotal of obsidian artifacts analyzed = 39. Subtotal of obsidan with use-wear = 37. Subtotal of independent use zones (IUZ) in obsidian artifacts = 93. There is 1 chert flake; 0 presents use-wear, with a total of 0 independent use zones (IUZ). There are 0 chert scrapers; 0 presents use-wear, with a total of 0 independent use zones (IUZ). Subtotal of chert artifacts analyzed = 1, Subtotal of chert artifacts with use-wear= 0. Subtotal of independent use zones (IUZ) in the chert artifacts = 0. Total of lithic artifacts analyzed: 40. Total of lithic artifacts with use-wear: 37. Total of independent use zones (IUZ): 93. The quotation marks around "Vega" and "Principal Group" indicate that these variables are alphanumeric and "" indicates the absence of data.
