     * the output tape will contain the ntemp2 final temperatures     *
     * specified.  it is necessary to have temp1.le.temp2(1).         *
     * if temp2.eq.temp1, the data will be thinned only.              *
     *                                                                *
     * restart    continue broadening an existing pendf tape.  all    *
     *            temperatures are copied through temp1.  additional  *
     *            final temperatures are added by starting with the   *
     *            data at temp1.                                      *
     *                                                                *
     * bootstrap  if bootstrap is not requested, each final tempera-  *
     *            ture is generated by broadening directly from       *
     *            temp1 to temp2.  if bootstrap is requested, each    *
     *            final temperature is broadened from the preceding   *
     *            temperature.  this option is faster due to the      *
     *            thinning in the previous step.  however, errors     *
     *            accumulate.                                         *
     *                                                                *
     * thnmax     the upper limit for broadening and thinning is the  *
     *            lowest of the input value of thnmax, the lowest     *
     *            reaction threshold, or the start of the unresolved  *
     *            range.  if there is resolved-unresolved overlap,    *
     *            the overlap region is included in the broadening.   *
     *            a negative value of thnmax will override the        *
     *            resolved and threshold limits.  This allows the     *
     *            first few threshold reactions to be broadened if    *
     *            desired.  the magnitude of thnmax must be chosen    *
     *            to keep the number of broadenable reactions less    *
     *            than or equal to the maximum of ntt (10).           *
     *                                                                *
