### Prior question

Posted:

**February 21 2018**Hi ,

When introducing the a new variable and its prior in params_CMB_default.ini, we have the following format.

center, min, max, start width, propose width

this I assume is a flat prior. Why are we entering a Center value when max and min are given? Is there some special reason for inputting this ?

The reason I ask is because when I make the likelihood plot for my new variable , I see my peak is always near the center value I enter.

Any Insight is appreciated.

Thanks
