Gemini - Canadian-specific information for Phase I – 2014B


A call for proposals for Semester 2014B has been issued by the Gemini Observatory. The Call for Proposals can be viewed at: Call for Proposals

The deadline for the receipt of Canadian proposals is:

Monday March 31, 2014, 4 P.M. (Pacific Daylight Time)

Note that not all Gemini partners have the same deadline and those involved in joint proposals need to submit their proposals by the PI's country's deadline.

Large and Long Program Proposals should be submitted by the Gemini Staff proposal deadline which is March 31, 2014 at 23:59 HST (Hawaii Standard Time).

Canada will have access in 2014B to: a total time of: 231 hours on Gemini North and 191 hours on Gemini South.


All instruments are offered in queue and classical mode, except for Laser Guide Star AO (Altair or GeMS) which are queue mode only for the moment. The instruments available on Gemini-North are GMOS-N, GNIRS, NIRI (imaging only), NIFS, and Altair; and on Gemini-South are GMOS-S, Flamingos-2 (in imaging and longslit mode only), GSAOI and GeMs, and now GPI offered in a shared-risk mode. Please consult the target accessibility page for important information concerning the RA restrictions for each instrument. There are also two visitor instruments offered in 2014B at Gemini-North (subject to demand): the DSSI Speckle Camera and TEXES.

To see more details about each of the instruments available for 2014B, please see the Gemini Call for Proposals.

What's new in 2014B

  • New exciting opportunity: Bring one, get one! In 2014B Gemini Observatory will subsidize, with up to US$2,000, the travel expenses of individual undergraduate and graduate students visiting Gemini-North or South, when accompanying a senior observer.
  • GPI (Adaptive Optics 0.9 to 2.4 micron imaging/polarimeter/integral-field spectrometer) is offered for 2014B, in shared-risk mode.
  • GMOS-S will receive new Hamamatsu CCD detectors, pending commissioning in July.
  • Large and Long Programs proposals will be accepted for observations beginning in 2014B. Further information on the process can be found on the Large and Long Program page.
  • Flamingos-2 will be offered in imaging and longslit mode. MOS mode is not offered at this time. Please check the Flamingos-2 Status and availability page for the most up to date information on delivered image quality.
  • GSAOI and GeMs will be available with targets restricted to RA 19h to 12h and Dec -75d to +15d. Please check the guide stars limiting magnitudes. PIs must check the availability of Guide Star constellations using the Observing Tool (OT) before submitting a proposal. Observations in IQ85 are possible and are encouraged for semester 2014B, for programs that can use delivered images with FWHM of 0.2 arcsecs as opposed to < 0.1 arcsecs delivered in IQ70 and IQ20 conditions.
  • Targets are limited at Gemini-North to 17 < RA < 13.5 and -37 < dec < +90; and at Gemini-South to 16 < RA < 12 and -90 < dec < +28. Please consult the target accessibility page for specific RA restrictions for some instruments.
  • There will be a minimum of 5 classical nights available on Subaru. All the instruments are available: COMICS, FMOS, FOCAS, HDS, IRCS, MOIRCS, Suprime-Cam, and Hyper Suprime-Cam in shared-risk mode. The following visiting instruments are also available: HiCIAO, Kyoto3II, RAVEN, and SCExAO. Proposals using these visiting instruments must include the relevant PI as a Co-I. Please view the full call for proposals for details. Please make integer nights proposals only.
  • Warning: when submitting your proposal, you should see in the PIT "Submit" tab the status updated to "Success", and receive a reference number for the proposal, such as "CA-2014B-003". If you do not see this reference number then the proposal might not have been received, and you are advised to please check with us at

Other Things to Note for 2014B

  • All proposals for Rapid Target of Opportunity (RToO) follow-up must submit a separate proposal for Standard Target of Opportunity follow-up (SToO) in conditions better than SB/CC/IQ=Any, if such follow-up is planned.
  • Poor weather and Director's Discretionary Time proposals can now be submitted at any time via PIT directly to Gemini (bypassing CTAC).
  • Since 2011B, fewer queue proposals are being scheduled in Band 3. The queue time will be filled to 80% of the advertised time, with the boundaries for Band 1 at roughly 30%, Band 2 60% and Band 3 80% of the available queue time. A new Cloud Cover constraint of CC80 has been defined, corresponding to 1 magnitude of extinction, or 40% transmission.
  • The minimum request for classical observing programs has been lowered from 3 nights to a 1 night minimum. The minimum time block that can be requested in queue-mode is no longer limited to 1 hour minimum.


  • Canadian astronomers must use the Gemini Observatory Phase I Tool (PIT) to prepare and submit their proposals. The new version of PIT for Semester 2014B must be downloaded from the PIT installation site. Since last semester a new "Experimental Design" section has been added, to give more space to the proposal description. The science justification, experimental design and technical justification are now to be entered in a latex file (or doc file if using the Windows version of PIT). Also the PIs are now strongly encouraged to include the output from the Instrument Time Calculators in the PDF. See the PIT page to download the new PIT. Please download the latex/doc/sty template files to write the proposal. For Canadian proposals, please use the default GemPhase1.tex, GemPhase1_14B.sty and GemPhase1.doc template files. Please allow extra time to familiarize yourself with the new PIT, and consult the help pages for the new PIT, which includes video tutorials too. Also, please note that, with the new PIT, a single proposal may now request time from either or both of Gemini-North and Gemini-South (it is no longer necessary to submit two separate proposals, however please indicate in the technical section how much time exactly is requested from each of Gemini-North and South).

Users will submit their finalized proposals from PIT; the proposals are sent electronically to NRC. The CGO will be in charge of the technical assessment of the proposals, which will then be reviewed and ranked by CanTAC.

All data will be subject to the normal Gemini proprietary period of 18 months.
