TRIS Data Products at LAMBDA
The TRIS experiment performed absolute measurements of the sky brightness in a sky circle at declination +42 degrees at the frequencies 0.60, 0.82, and 2.5 GHz, using geometrically scaled antennas with identical beams (HPBW 18 degrees x 23 degrees). The TRIS group used the data to separate the different contributions to the sky emission and to evaluate the absolute temperature of the CMB at 0.60, 0.82 and 2.5 GHz.
