the unit of gencost coefficients

[122020316]

Hi Prof. Zimmerman,

I want to ask the unit name （for example: $/(MWh)） of the coefficients in the last 3 columns of gencost matrix in case file. 

In case file,

mpc.gencost = [

2 0 0 3 0.02 2 0;

2 0 0 3 0.0175 1.75 0;

2 0 0 3 0.0625 1 0;

2 0 0 3 0.00834 3.25 0;

2 0 0 3 0.025 3 0;

2 0 0 3 0.025 3 0;

];

What's the unit of "0.02 2 0;" in the last three column, respective, please?

Thanks a lot.
