Typical Collection Units are cores, sections, and excavation units. A Collection Unit is located spatially within a site and may have precise GPS latitude-longitude coordinates. For pollen data, a Collection Unit is typically a core, a section, or surface sample.A Collection Unit can also be a composite core comprised of two or more adjacent cores pieced together to form a continuous stratigraphic sequence. For faunal data, a Collection Unit could be as precise as an excavation square, or it could be a group of squares from a particular feature within a site.

BP stands for “Before Present” or “Before Physics” as some would refer to it.The lat-long box can circumscribe the site, for example a lake, or it may circumscribe a larger area in which the site lies either because the exact location of the site is not known or because the exact location is purposely kept vague.In the case of many legacy sites, the exact location is not know precisely; for example, it may have been described as «on a gravel bar 5 miles east of town».You can calibrate a single radiocarbon date with, e.g. given is optional and only used for summarising and plotting.

If you find bugs or want to suggest new features please visit the Bchron Git Hub issues page. Once in R you can type: Bchron will calibrate single or multiple dates under multiple (even user defined) calibration curves.
