BData for this entry were determined on some or all of the following
shots: 8A-326, -331, -332, and -333; each was fired using several
plate thicknesses.
YShots 8A-331, -332, and -333.

entry, five each on the last five, four each on the four single-asterisk
entries marked a, and three determinations

The data\ at 6.31 mm seem anomalous, but no good reason for discard was found.
Linear least squares fitting of all the data gives Ur, = 3.633 km/s - 0.01184 t (mm).
At t = 0, plate U, = 7.770 km/s and P, = 38.88 GPa. Acoustic approximation with
D = 8.642 pox = 1.768 g/cmS, and porn = 2.787 g/cm3 gives corresponding explosive
parameters, of P, = 33.16 GPa, U,, = 2.169 km/s, and y = 2.984.
