Río Tonosí Valley Settlement Dataset
Charles A. Berrey

Collection Lot Data

The data files LOTDATA.TXT and LOTDATA.XLS contain data on the size, type, and contents of each collection lot in the Río Tonosí valley survey. LOTDATA.TXT is an ASCII text file, and LOTDATA.XLS contains the same data in the form of an Excel spreadsheet. Each line represents one collection lot. There are 1228 lines in the text file, each with 19 variables separated by commas. The variables are, in the following order:

1

Collection lot number.

2

Area (ha) of the collection lot.

3

Collection Type:
Probe=shovel probe
Surface=surface collection

4

Shovel probe area (m²).

5

Shovel probe volume (m³).

6

Number of El Indio sherds recovered.

7

Number of La Cañaza sherds recovered.

8

Number of Bijaguales sherds recovered.

9

Number of sherds recovered that could not be assigned to a chronological phase.

10

Total number of sherds recovered (the sum of variables 6-9).

Estimated Residential Densities

The following variables present the average, minimum, and maximum residential densities for each phase, as estimated using the method discussed in Chapter 2 of the corresponding dissertation.

11

Average residential density (people/ha) for the El Indio phase.

12

Average residential density (people/ha) for the La Cañaza phase.

13

Average residential density (people/ha) for the Bijaguales phase.

14

Minimum residential density (people/ha) for the El Indio phase.

15

Minimum residential density (people/ha) for the La Cañaza phase.

16

Minimum residential density (people/ha) for the Bijaguales phase.

17

Maximum residential density (people/ha) for the El Indio phase.

18

Maximum residential density (people/ha) for the La Cañaza phase.

19

Maximum residential density (people/ha) for the Bijaguales phase.

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

A001,0.42,probe,0.17,0.07,0,1,2,7,10,,7.5,7.5,,5.0,5.0,,10.0,10.0

This indicates that the data pertain to collection A001, which represents a lot of 0.42 hectares. The type of collection was a shovel probe with an area of 0.17 m², and a volume of 0.07 m³. This collection yielded a total of 0 El Indio sherds, 1 La Cañaza sherd, 2 Bijaguales sherds, 7 sherds that could not be assigned chronologically, for a total of 10 sherds. The average estimated residential density (people/ha) is 0 for the El Indio phase, 7.5 for the La Cañaza phase, and 7.5 for the Bijaguales phase. The minimum estimated residential density (people/ha) is 0 for the El Indio phase, 5.0 for the La Cañaza phase, and 5.0 for the Bijaguales phase. The maximum estimated residential density (people/ha) is 0 for the El Indio phase, 10.0 for the La Cañaza phase, and 10.0 for the Bijaguales phase.

The last, or 1228th, line of the ASCII text file is:

B280,0.55,surface,,,0,2,0,1,3,,7.5,,,5,,,10,

This indicates that the data pertain to collection B280, which represents a lot of 0.55 hectares. The type of collection was a surface collection, hence no probe area or probe volume is provided. This collection yielded a total of 0 El Indio sherds, 2 La Cañaza sherds, 0 Bijaguales sherds, 1 sherd that could not be assigned chronologically, for a total of 3 sherds. The average estimated residential density (people/ha) is 0 for the El Indio phase, 7.5 for the La Cañaza phase, and 0 for the Bijaguales phase. The minimum estimated residential density (people/ha) is 0 for the El Indio phase, 5.0 for the La Cañaza phase, and 0 for the Bijaguales phase. The maximum estimated residential density (people/ha) is 0 for the El Indio phase, 10.0 for the La Cañaza phase, and 0 for the Bijaguales phase.
