... NFILTCAR is the logical rather than the physical number of carriers; if two or more filter wheels are encoded as a single character in the data, there is effectively only one filter wheel, as far as data handling is concerned. If one filter mechanism carries chromatic filters and another carries ``neutral'' filters, the total number of bands (i.e., rows) in the table should be the product of the number of positions in the two carriers. ...
