I am currently working on a project where there is one heated plate and i take temperature measurements over it with the help of 3 different thermocouples (which have the same distance from the plate surface) at different heights. Each thermocouple at each height has n=320000 data points (temperature measurements), that can be displayed graphically as a probability distribution which reminds a normal one. I would like to know if there is a way to fit multiple univariate normal distributions on the one produced by the data that could describe it as well as possible.Thanks in advance.
P.S. I have attached a file that shows the produced distribution (which looks a lot like a normal one) of the third thermocouple at height z=2mm
