In my understanding, unbiased electron density map usually refers to the Fo-Fc map.But I have seen in some papers sentences like that "The initial, unbiased 2FoFc map is contoured at".I was a bit confused since I was told by my instructor that the 2Fo-Fc was usually biased.

Can anyone clear up this concept for me?
