Jodrell_Bank (Eskil Varenius at Fri May 25 19:47:13 2018) Minor failures:RECE

C-band receiver error, LCP bandpass wiggle. Seems fairly stable in time so should be able to calibrate out using e.g. BPASS.

Jodrell_Bank (Eskil Varenius at Fri May 25 19:47:34 2018) Minor failures: POIN

Jb Mk2 may have (directional dependent) pointing errors of up to 70 arcsec. Self-calibration may be needed to obtain best possible results.

Jodrell_Bank (Eskil Varenius at Fri May 25 19:47:48 2018) Minor failures: TSYS

A priori flux density calibration very uncertain. Work in progress to improve, but for now it may be wise to set the amplitude scale using nominal SEFD values and then self-calibrate.

Onsala (Jun Yang at Mon Jun 04 10:15:46 2018) Success:

At S and X bands, Onsala has started to use 80Hz calibration system in this session. The new T-Cal is about 3 K at X band and 7 K at S band.
