It is suggested that these selection effects are responsible for the apparent overabundance of S types among the NEAs and that this overabundance is in part a result of the larger phase darkening of the C types over the S types. The large phase angles and preferential phase darkening of the C type NEAs force some of them below the threshold of detectability (in a magnitude-limited survey), thus exaggerating the number of S type NEAs.
