STATISTICS
• During 1999 and 2000, the National Facility was in operation
for an average of 8.2 months each year
• During the operating period, MERLIN observations were
made for 83.2% of the time. A further 5.7% of the
operating time was taken up by frequency changes requested by
PATT
• 92% of MERLIN PATT Priority A observations and 86% of
Priority B observations were completed successfully
• 160 proposals were received for the use of MERLIN during
Semesters 99A, 99B, 00A and 00B. 86% of these had at
least one UK proposer and 66% had UK PIs
• The number of MERLIN proposals received during
Semesters 99 and 00 was very comparable with that in the
previous 2 years. The "oversubscription" factor was
~2.6
• During 1999 and 2000, 276 individuals were named on
MERLIN proposals. 117 of these were based in the UK, from
26 different institutes
• Excluding JBO researchers, 33 separate MERLIN observers
came to the National Facility to process their data during
1999 and 49 during 2000. Some came on more than one
occasion. Particular visits were for as short as one day or
as long as two months, with a typical duration of
approximately 10 days. Data processing was also carried
out by National Facility staff for 38 observers in absentia
during the combined period 1999 and 2000
• The National Facility was scheduled to take part in 2328
telescope hours of VLBI observations during 1999 and 2000.
The success rate was 93.6%
• During the period 1999 to 2000 the EVN programme
Committee received 135 proposals, of which 21 had UK
PI's and a further 20 had UK Co-I's
• The number of papers based on National Facility
observations published in refereed journals has increased
again during the period covered by this report. The average
yearly publication rate now stands at ~50
