Mobility Calculation related Query

[anindya@iiita]

Dear Experts,
I am following the tutorial of epw school 2018 for the calculation of mobility and I am having a few queries,
1.Can I use random grids or fine grids instead of filkf & filqf to compute the mobility in epw1 and epw2 file?
2.Apart from the difference wrt epw1.in, other parameters (like wdata,4 cartesian and all) should be exactly same in epw2.in?
3.Which file will be generated at the end of calculations(after having epw2.out) to plot the mobility vs temperature curve?
I will be waiting for the response.

Thanks and regards,
