What is the test for a motion to exclude evidence in a sexual assault case?

When the defendant seeks to exclude evidence under the authority of this section, "the record must affirmatively show that the trial judge did in fact weigh prejudice against probative value.... [T]he reason for the rule is to furnish the appellate courts with the record necessary for meaningful review of any ensuing claim of abuse of discretion; an additional reason is to ensure that the ruling on the motion 'be the product of a mature and careful reflection on the part of the judge'...." (People v. Green (1980) 27 Cal.3d 1, 25, 164 Cal.Rptr. 1, 609 P.2d 468.)
