Help with OxCal online

[Marco Liberatore]

Hi everyone, 

I would like to see if I am doing it wrong using OxCal online or if there is a problem with the software.

 
I need to calibrate a number of conventional ages using the Marine20 curve and a local reservoir effect already calibrated with M20. I entered, as instructed, the settings but I realized that the calibration is done on M20 but the reservoir correction was not considered. This caused me huge problems because for a while I thought the ages calibrated on Marine20 were younger by 150-200 yr (the reservoir correction) than the ages calibrated on older curves!
So I would like to understand: how to insert the setting correctly?

This is how I entered the settings. Actually, I tried also to insert the Delta R in the lower panel (plot) but nothing changed. 

  

These are the results, they are calibrated on M20 but reservoir effect of -142 +-/66 is not in the results. I have calibrated the same with MatCal code on matlab and, for example,

AYD4 sample should be 4834-4388 cal. yr BP and not 4601-4245.

The Curve and Delta_R commands should be within the main model (that is in the Plot() holder) not in the Options box. The Options box should normally only be set using the Tools > Options - though people may wish to edit this manually for some purposes.

In your case the Curve() and Delta_R() functions should be copied to the top of the Plot() box. This is probably easiest to do in Code view.
