JLS Current Status

This page details and reports on the current state of the JCMT and JLS specific instrumentation and the overall progress of the JLS. It will be updated once a month after every JLS observing run on the JCMT.

Date: 23 September 2009

 

TELESCOPE

 

The telescope has operated well during recent JLS observing blocks.
 

SCUBA-2

 

The science grade arrays were installed into SCUBA-2 which was then cooled down. Array set up and integration testing has already commenced after which on sky commissioning will begin in October.
HARP/ACSIS The front page of the JCMT instrument page now provides brief summaries of the current status of the instruments. Additional:
  • Receptor H14 has been switched off and this has improved the performance of the array as a whole.
 

CALIBRATION

 

No new news. No evidence of striping has been reported or observed for a number of months now.
JLS PROGRESS There have been four JLS observing runs since the last Status update, which were supported by all the JLS teams (see the occupancy pages to see who observed for which team).

From those runs, there were 282 hours scheuled of which 125 hours were observed in the JLS queue. The was a lot of time available in band 3-4 weather which allowed the SLS to obtain a lot of data for their survey. There were about 125 hours observed in the national queues with just 12.5 hours lost to weather. There were almost 14 hours lost to faults.

The current progress is shown in the bar charts below, illustrating the amount of time charged to each survey and the current completion rate (for just the HARP survey components). The figures have been updated to reflect the new allocations following the JLS2008 review.

At the time of writing, the NGS are approximately 88% complete, the GBS are approximately 60% complete on the HARP portions of their surveys, while the SLS are now 57% complete.

For reference, the JLS allocations (updated following the JLS2008 review) are available here.
