Arguments

`fname`	a `character` vector giving the file name of the fh file.
`BC_correction`	a `logical`. If TRUE the correction moves BC-dates one year forward.

`ids`	A `data.frame` identifying the series. Always contains columns `"tree"` and `"core"`, may contain columns `"site"`, `"radius"`, and `"stemDisk"`. All columns are `numeric`.
