UKIRT Statistics Semester 03A




The UKIRT statistics below cover the areas Applications and Allocations,Observing and Completion, Faults, and Publications. Clicking on an image will show you the full image. Click on your browsers 'Back' button to return to this page.

Applications and Allocations
UKIRT had 57 applications for semester 03a, of which 35 were allocated time. The plot to the left shows the requests and allocations by instrument. 1976.5 hours, plus 14 mornings for a visiting instrument, were requested this semester. 869.5 hours were allocated, plus the 14 mornings, leading to an oversubscription of 2.27


UK institutions accounted for most of the applications, but applications from the US, Korea, and European countries other than the UK (plot to left) were also received. The plot to the right shows the number of proposals from UK universities.
This plot shows the science categories covered by the proposals in semester 03A.

Observing and Completion of Programmes
UK PATT programmes averaged a completion rate of 77% this semester. In 03a, UKIRT was flexed for the first time, and so all programmes were observed under appropriate weather conditions. We classically scheduled programmes either because of the complexity of the programme, or because the programme involved monitoring targets. The plot to the left shows the average weekly completion rate for all of the flexed programmes, along with the hours lost to weather or used for engineering per week.The top 10 ranked programmes averaged a completion rate of 94%. The plot to the right showns the completion per week over the semester for each of the top 10 programmes



The plot to the left shows the completion by rank - the highest completion rates were for the highest ranked programmes, or for those programmes with no strict weather requirements. All programmes  are included in this plot. The plot to the right shows only those projects which were flexibly scheduled.
Generally, programmes requiring dry conditions fared the worst this semester. However, the complexity of the programme, and the timing of MSB submission had a fairly large affect on a  programmes completion.
Green bars indicate science observing, grey is engineering, and red columns indicate time lost to faults or weather. The three columns to the right give the totals.


Fault Summaries
These plots summarise the number of faults, and the time lost faults.

Publications
There are 32 papers published in peer-reviewed journals to June 27 this year. The plot to the left shows the publications by instrument.  Data taken in service mode accounts for 17% of the published papers. The plot to the right shows the time lag between observation and publication dates.
