This is a broad-band receiver with two orthogonal linear polarizations (at a 45°-angle with the horizon). The receiver delivers 4 basebands (each with two polarizations):
Baseband | Center Frequency | Bandwidth | Comment |
---|---|---|---|
1 | 5.250 GHz | 2500 MHz | beware of strong RFI at frequencies < 4.5 GHz! |
2 | 6.750 GHz | 2500 MHz | |
3 | 6.668 GHz | 200 MHz | for methanol observations |
4 | 4.829 GHz | 200 MHz | for formaldehyde observations |
Frequency [GHz] | Channel | Polarisation | Tcal [K] | Tsys [K] | Sensitivity [K/Jy] | SEFD [Jy] | Aperture Eff. [%] | TMB/S [K/Jy] | Main Beam Eff. [%] | HPBW [arcsec] | Last update |
