Yebes

• J. Gonzales: rate 1.17e-13 s/s, offsets in logs named n1k01?ys.log on vlbeer.
• Did not observe K and L due to heavy rain and broken shutter.
• Transferred the data of G, H, I, J, E.
• VEX freq block sidebands UUUU UUUU LLLL LLLL rather than the default UL UL ... from SCHED
• Epoch E: scan No0003 (142-0814) file empty or not recorded

Effelsberg

• U. Bach, etransferred epochs G & H. Pending transfer of the remaining epochs.
• Offset +19.3 usec in G
• Logs named ndk01g, ndk01h, and later n1k01i, n1k01j, n1k01k, n1k01l, n1k01e on vlbeer. 
• H-maser rate same as in GMVA f211a, i.e., 2.05e-13 s/s.
• VEX freq block sidebands UUUU LLLL rather than the default UL UL ... from SCHED.
• Epoch G: wind and bad weather, first part ot track unusable, not on source until ~18:30 UT

KVN Yonsei, Ulsan, Tamna

• Waiting for e-transfer...
• Table of clock offsets, sign for VEX same as in table
• H-maser rate?
• Tie of KVN to Ef+Ys : shift KVN VEX clocks by -2.83 us from kvn a priori values

DiFX

Special setup for correlation, because Effelsberg does not have simultaneous K and Q capability.

• One v2d file for K-band, with "freqIds=..." to select only K-band recorded frequency IDs
• Another v2d file for Q-band, with "freqIds=..." to select only Q-band recorded frequency IDs, and "deltaClock=.." to include any clock offsets over K-band reference clocks
• Zoom bands of 64 MHz due to KVN 2ch x 512 MHz, versus Ef and Ys with 64 MHz wide channels in USB/LSB
• Same zoom bands also added to Ef and Ys in order to produce all-USB visibility data; otherwise HOPS fourfit issues
