The coordinates (latitude and longitude, in WGS84 datum) give an indication of the accuracy of the location:
With 1 decimal place an error of ca 10 km (or more) is to be expected, with 2 decimal places of ca 1 km, with 3 decimal places of ca 100 m, with 4 decimal places of ca 10 m.
The last column gives an overall indicator of accuracy, based on the geographic location and the reliability of the source. 1 means very good, 2 good, 3 satisfactory, 4 questionable.
--------------------- Note 8 for Caiambe: Although covered by recent Amazonian sediments, horizontal charcoal remains have been observed in the lower third of the Ah, as in profile SP 6 in Belterra (see also Chap. 1.3 and 1.5.2).
