Gravitational-radiation-detector observations in 1973 and 1974

Results of observations of the Argonne-Maryland gravitational radiation detectors during the period May 1973-July 1974 are presented. Previously published data are corrected for a computer programming error. For certain continuous periods we observe an excess of coincidences over the accidental ones. The excess is more significant for the algorithm ${\left[\right(\frac{d}{\mathrm{dt}}\left)\right(x^2+y^2\left)\right]}^2$ than for the algorithm ${\left(\frac{\mathrm{dx}}{\mathrm{dt}}\right)}^2+{\left(\frac{\mathrm{dy}}{\mathrm{dt}}\right)}^2$. This gives information concerning pulse length and spectral character, and implies that published sensitivity calculations are not applicable to these experiments.
