Choosing Thermistor based on table - Marlin

Hi guys, bought a new hotend, but I'm afraid to turn it on because I don't know which Thermistor I have!

I have a table with Ohm values, but I have NO idea how to convert or compare this to anything that is in the Marlin firmware in the thermistor table.

Here is the information about the ohms at which temperatures:

Can anyone give me the golden clue?


Btw, found this:
[calculator.josefprusa.cz]

But I have no idea what r0 r1 r2 and !?BETA?! is.. I am lost.

Also, the list that the site regerates looks nothing like the list in my Marlin so I would have no idea how to implement the data in that list again in Marlin. Pffff.


Oh and here is the thermistor itself:
