UKIRT Statistics Semester 03B




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 47 applications for semester 03b, of which 37 were allocated time. The plot to the left shows the requests and allocations by instrument. 1467 hours, plus 14 mornings for a visiting instrument, were requested this semester. 837 hours were allocated, plus the 14 mornings, leading to an oversubscription of 1.75


UK institutions accounted for most of the applications, but applications from the US, Australia, 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 03B.

Observing and Completion of Programmes
UK PATT programmes averaged a completion rate of 72% this semester. 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 74%. 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 for flexed programmes. As shown in the plot to the right, programmes requiring dry conditions or strict seeing conditions fared the worst this semester. This semester, the largest affect on programme completion has been the 30% of time lost to weather.
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 64 papers published in peer-reviewed journals this year. The plot to the left shows the publications by instrument.  Data taken in service mode accounts for 13% of the published papers.
