This presentation, intended for discussion within TF Data Analysis RD-ASEP and not for conclusions, analyzes model performance using L_exp data from Annex_9_test_runs where both left and right sound were measured. Model performance varies across speed bins, with higher mean absolute error at low and high speeds. Adjusting theta_tr values improves mean absolute error across all speed bins. Testing without an envelope function results in more measurements exceeding expected values, requiring extra margins.
