A COSMIC MICROWAVE BACKGROUND-RADIATION MEASUREMENT REPRODUCED - A STATISTICAL COMPARISON OF MSAM1-94 TO MSAM1-92

The goal of the second flight of the medium-scale anisotropy measureme nt (MSAM1-94) was to confirm the measurement of cosmic microwave backg round radiation (CMBR) anisotropy made in the first flight (MSAM1-92). The CMBR anisotropy and interstellar dust emission signals from the t wo flights are compared by forming the sum and difference of those por tions of the data with the same pointings on the sky. The difference d ata are consistent with a null detection, while the summed data show s ignificant signal. We conclude that MSAM1-92 and MSAM1-94 measured the same celestial signal.
