This will be because in general OxCal takes astronomical year dates as the input. There is more

Hi Kelly – 1. You can do a single P_Sequence and change the ΔR midway (see code below). R_Dates will

Dear John and Erik, Ok, now I had time to check out the model results. First, I ran V_Sequence models
