Under these ciremstances che

of X-ray and total cheraal energy.
Heat leakage inco the calorimecer compartment after secoud-stazge firing
was unfortunate.
This beating effect was sose evident in aidsecctions where
the instruments were designed to look radially outward, which lends support
to the theory that the beat came frow an internal source rather than froma skin
beating, since these were better insulated against skin heatirg than vere the
transducers mounted on the projecting doors.

Also, no heating occurred before second-
stage firing in the higher density air.
