+247a,"When using entry 10, the lower limit is used to encode the quantile q (must be an integer between 0 and Q) while the upper limit is used to encode the total number of quantiles Q. This defines the probability of the parameter falling within quantile q. For instance, to encode the probability of falling within the 10th percentile, then q=10 and Q=100; to encode the probability of falling within the 1st tercile, then q=1 and Q=3."
