SPLAT should have written the CQ table out correctly.  If you set
SUBARRAY then the CQ table should include the data from that subarray
renumbered as subarray 1.  If you did not set SUBARRAY, then it should
include all data with the subarray not renumbered (or renumbered to 1
if APARM(3) > 0).  Not knowing how adverbs were set, I don't know how
to evaluate this.
