Dear Observatory Staff and Global 3mm VLBI PIs,

Please find below Version 1 of the Block Schedule for the coming
Global 3mm VLBI session in May. 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 is being observed. 

===> Please contact him by 6th APRIL
                           *********

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

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.

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.

Polarization
------------
Note that projects GF016, GM065C and GA024F 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)
