Temperature fields on visualization tool

Hi,

I am trying to reproduce some temperature maps that I get from the "Visualize Galaxies and Halos" tool, but I am not completely sure of the difference between the three fields present there: temp, temperature, and temp_sfcold.

What is the difference between temp and temperature?

I suppose temp_sfcold is the temperature assuming star-forming cells have a certain fixed T < 10^4 K. What exactly would be the value of this temperature? (Sorry to bother with this simple question, but I could not find a clear answer in the methods papers)

The first two temp and temperature are the same (right?), they are just aliases.

And you are correct, temp_sfcold sets star-forming gas to be at its cold-phase temperature (as per the TNG model, and original description in Springel & Hernquist 2003, this is 1000 K).
