+Hobart windstowed 2255-2317, 2330-End of experiment.
+Discovered a problem with the Vex file related to the fanout used. The Hobart rack is set for geodesy (not a VLBA-style rack) which caused problems with the fanout mode used. To correct this, the SCHED setup was changed to:
+station=HOB_MK5\\
+m4patch=geo1\\
+format=MKIV1:2\\
+ifchan='2N','2N','1N','1N'\\
+bbc=11,12,3,4\\

+The VEX file has this track assignment:

+def MKIV.4Ch2bit1to2;\\
+  *  mode =  1    stations =Ho\\
+  *     format = MKIV1:2, and fan-out = 2\\
+  *     mode requires  16.00Mb/s/tr; stations using disks\\

 This configuration gave good fringes (at X-band) to the other Australian telescopes.
