The minimum azimuthal error amplitude occurred in the 60[degrees] GFOV condition, and there is evidence (see Figure 9 in McGreevy & Ellis, 1986) that the azimuthal error amplitude in their study increased in the 30[degrees] and 120[degrees] GFOV conditions.
Azimuthal errors were largely attributable to an increase in front/back confusions, suggesting that spectral features in the 3- to 6-kHz region, which are believed to contribute to front/back discrimination (Shaw, 1997), were disrupted by the HPDs.
