In superstring backgrounds with only NS-NS fields turned on, or in flat space, one needs to introduce \"non-minimal\" variables in order to construct the b antighost. However, in Type II backgrounds where the Ramond-Ramond bispinor field-strength satisfies certain conditions, the b antighost can be constructed without the non-minimal variables.
