Dear Observatory Staff and Global 3mm VLBI PIs,

Please find below Version 2.0 of the Block Schedule for the coming
Global 3mm VLBI session in October. The projects which are scheduled have
been approved by the VLBA Scheduler and myself, on the basis of the
proposal reviews in Europe and at NRAO.

Thomas Krichbaum will assist in making an integrated observing
schedule for the session, and PIs are asked to contact him, to specify
to what extent they wish to be involved in the schedule making for the
part of the schedule when their source(s) is (are) being observed.

===> Please contact him by 8th SEPTEMBER.
                           *************

The final, integrated schedule for the session will be made available
to the observatories by 22nd SEPTEMBER, 2 weeks before the start of the
session on 6th OCTOBER.


Antennas
--------
The antennas available at the VLBA are NL,FD,LA,PT,KP,BR,OV,MK.  The
European telescopes ("Eu" on the block schedule) are Pico Veleta,
Plateau de Bure, Effelsberg, Onsala-20m and (possibly) Metsahovi.
The Yebes 40m telescope may take part for some or all of the observations.

Recording mode
--------------
All GMVA continuum projects will be observed with a recorded bit-rate
of 512 Mb/s, since at 3mm wavelength the short atmospheric coherence
is the main limitation to detection sensitivity. All observatories
will record using MK5 disk systems, with correlation at the Bonn DiFX
software correlator.  MK5 disk availability, and VLBA disk-change
logistics will determine the fraction of the scheduled time which can
be spent recording data.  Walter Alef will make a final decision on
this when all the constraints have been considered.

7mm scans at VLBA
-----------------
Both GF017B and GM066B will also observe some 7mm scans between
3mm scans at VLBA antennas.

Polarization
------------
Note that GF017B and GM066B both request dual LHC+RHC
recording at observatories where this is possible.

General considerations
----------------------
===> Please contact me (porcas@mpifr-bonn.mpg.de) IMMEDIATELY if you find
     any mistakes or problems with this version of the schedule.

Regards

Richard Porcas
(European Global 3mm VLBI Scheduler)
