COP is energy out divided by energy in.
You will need to capture the amount of energy going into your system.
You will also need to capture the amount of energy coming out of your system.
...then divide the latter by the former. If you want specific assistance in setting up your own test, please tell me exactly what you need to know in order to proceed, and I'll try to assist.
I wish you the best in your own project, don't forget the photographs.

Please don't be so defensive, I'm simply being curious.
I would be neat to use your test results as a baseline comparison for my setup when I get there. But it's impossible to compare when I don't know what exactly you were testing. Looking at some dots on a graph doesn't tell me a lot if I don't know what it represents.
I understand that "heat" and "chill" were temperature measurements of the two barrels. I have only guessed that "LS temp" and "HS temp" were readings at the heat exchangers, "HS press" and "LS press" were refrigerant pressures at the heat exchangers, and "super heat" and "sub cool" were measurements of the water leaving the exchangers but before mixing with the barrel water.
And for COP I assume you were using a temperature approximation (Th/(Th-Tc) and not volumetric heat gain/loss, but I have no idea whether you were using the barrel temps or the heat exchanger temps or pre-barrel output temps, etc.
If you could elucidate that would be helpful/informative.
