All receivers are uncooled.
1 Using standard LBA frequencies. The wide bandwidth means that for frequencies within ~ 100 MHz of these frequencies should have approximately equal CAL values.
2 Using 1934-634 at elevation 61deg - LJH
Gain curve at 6.7GHz (LJH 2024): DPFU = 0.1240 + 9.295e-4*el - 8.673e-6*el^2
