best way to insert luminescence dates

[Max Langridge]

Probably an easy question, but I see some differences in how different users do this (or their results come out differently.

So, what is the best command/method for inserting luminescence dates into OxCal We have been using C_Date, then subtracting the value from 2020 CE, so that a lum date of 4000 +- would be -1880+-

This is in a model that also has the occasional C-14 date

Thanks, Rob

There is some information on this at:

Best wishes

Christopher

Hi Rob,

I would suggest a one-step approach. C_Date can work for this, but also a normally distributed Date. For example, for a date of 1300±90 that uses 2020 CE as present:

Date("TL lab code __",N(2020-1300,90));

Hope this helps, Erik
