F182A Correlation Report
Fringes
Station | Code | Fringes | Plots | Comments |
Ef | B | Yes | | Nearly perfect conditions: sunny, no clouds. Pointing drifts slightly, probably because the antenna is heating up in the sun. Tsys ~170K during scan No0001 |
Mh | Z | Yes | | good weather. swapped pols, the steup will stay the same for c182a, but before c182b will be fixed. |
On | X | Yes | | Tsys ~400K during scan No0001 |
Ys | Y | Yes | | An amplifier burned out, likely just before the test. Frontend signal switched to a spare channel to compensate, but too late to influence these results. This explains low SNR, but not why we see fringes to R only (Ys normally only records LCP at 3 mm) |
Pv | P | Yes | | bad weather |
