This section contains instructions for configuring GPI at phase II. It is organised as follows:
The purpose of these page is to give quick guidelines to both Contact Scientists, NGO's and PI's to make sure that the defined observations in the OT are correctly defined.
The Phase II check point of view GPI consists of 4 components as these are driving the Phase II checking.
A Gemini Facility Calibration Unit (GCAL) is available on each Gemini telescope, providing continuum and line emission light sources for wavelength and flat-field calibrations. Each GCAL is located permanently on one port of the instrument support structure and light is directed into an instrument by the science fold mirror. The GCAL optics simulate the f/16 telescope beam, illuminating the instrument pupil in the same way as light from an astronomical source.
This section describes both the data format for all Gemini instruments, including GMOS, and the Gemini IRAF Package, which supports imaging, as well as long-slit, multi-object, and IFU spectroscopic data from both GMOS-N and GMOS-S.
Gemini is pleased to announce the launch of 4 feasibility studies as a result of the GIFS RfP process. The four studies (alphabetically) are GEONIS, GMOX, MOVIES, and OCTOCAM. Below is a brief synopsis of each study:
Left: J-band polarized intensity (P⊥) images. Right: P⊥ scaled by r2, where r is the distance in pixels from the central binary, corrected for projection effects. Both images are shown on a linear scale and oriented north up and east left. The coronagraph is represented by the black filled circles.

Commercial power has been restored to Cerro Pachón, and the road will be passable for a delivery of fuel for the backup generator on Monday. Thus, we will be resuming science operations early next week.
The region of Re50 and Re50N observed in 2006 with SuprimeCam at the Subaru telescope, and in 2014 with the Gemini Multi-Object Spectrograph (GMOS) at the Gemini South telescope. A [SII] filter was used for both images. The seeing was in both cases 0.5 arcsec. Each image is about 3 arcmin wide. North is up and east is left.
