Status and Availability

Update March 24, 2014

 

  • The Early Science programs have been selected and the PI's contacted and they now can work on the Phase II for the observations. 
  • The second commissioning run started on March 20th and has been a great success, and it is expected that the remaining two nights will be working as well. The run has shown that the ADC is working and it is expected that we can use the ADC as part of the standard operations. Major improvements to the OIWFS control loops have been implemented and work is in progress on analysing the data. The polarization modes have been used frequently to obtain more performance data, high contrast data with the standard coronography and direct imaging data has also been taken. NRM observations has also been taken, which will allow performance evaluations of this mode in time for the 15A CfP. 
  • It is planned that April 20th to 26th will be the allocated nights for the Early Science run. 
  • Currently the time estimates in the OT is wrong as it does not properly calculate the times needed to take an exposure. Please check the Overheads node for more information. 

 

Update February 25, 2014

There has been a lot of activity on the GPI side these last few weeks.

 

  • GPI Early Science has been opened with a deadline of February 28th, 2014
  • WWW pages has seen a major overhaul:
    • Instrument Performance pages has seen a major update to all subsection
    • The Campaign target list has been updated
    • The public data realease now has more than a dozen targets that can be downloaded. The data sets include both raw and reduced data.
  • The remediation was a success, it included:
    • Replacement of two motors (pupil and prism/disperser slide)
    • Installation of an IFS baffle that removed the stray light seen on sky flats and GCAL flats
    • Software fixes that among other things decreased the overheads in readouts by 4 seconds
    • Most importantly a synchronization of the CCR's that decreased the measured vibrations by at least a factor of two

Update September 13, 2013

GPI is currently in the Acceptance testing stage, which is expected to conclude with the Acceptance review in late May 2013. Assuming the current schedule, the instrument will be delivered to Gemini South in middle 2013. GPI will be used to carry out large Campaign programmes as well as standard science programmes via the TAC system. It is expected that the earliest science observing will be in semester 2014A pending results from Acceptance Testing and Commissioning.

The approved GPI campaign program is led by Bruce Macintosh (Lawrence Livermore National Laboratory) and will conduct a comprehensive survey to yield a robust census of extrasolar giant planets, for more information visit this link.

GPI is currently under development. Assuming the current schedule, the instrument will be delivered to Gemini South in middle 2012. GPI will be used to carry out large Campaign programmes as well as standard science programmes via the TAC system. It is expected that the earliest science observing will be in semester 2013A pending results from Acceptance Testing and Commissioning.

The Gemini Planet Imager (GPI) traveled from the University of California Santa Cruz to Gemini South and is now on the summit of Cerro Pachón. GPI remained in crates during the busy Gemini South maintenance shutdown. Unpacking just began, and GPI was reassembled in the instrument lab on August 29. If everything checks out successfully, GPI will be mounted on the telescope at the very end of October, with first light on sky sometime during November. Because no on-sky commissioning has been completed yet, the instrument will not be part of the regular 2014A call for proposals. However, we are aiming to conduct some early science observations, selected through an open call to the community, during the semester. More details will be provided as the instrument commissioning proceeds.

Update February 27, 2013

GPI testing at Cerro Pachon have reached a major milestone yesterday by taking images of the calibration light source with the science camera. The final contrast curve is very similar to those obtained in Santa Cruz. Today we ran the Speckle Nulling routine giving an improvement of a factor 2 to 3 . Progress have been according to the telescope integration plan and it is expected that GPI will go onto the flexure rig in the last week of September.
