  \caption{Ratios between LWS~02 observations and TPM predictions,
           weighted mean values and standard deviations per detector
           (SW1, 2, 3, 4, 5 and LW1, 2, 3)
           and per asteroid. The photometry of the LW4 and LW5 detectors
           is less reliable due to dark current problems.
