Gemini Planet Imager (GPI): Cleared for Shipment to Gemini South!

In a milestone statement distributed moments ago by the GPI Pre-delivery Acceptance Review Committee, Chair Stephen Goodsell announced that GPI is now clear for shipment from the University of California Santa Cruz to Gemini South in Chile.The Committee’s final report is slated for release on July 26th, but a statement sumarizing the results of the review is available now - GPI Review Committee: Final Day Statement  41 KB

GS observing database offline Jan. 23 during UPS maintenance

The Gemini South observing database will be offline for most of the day on Monday, January 23, during maintenance to the Uninterruptible Power Supplies on Cerro Pachon. All GS ODB services including program sync, attachment transfer, guide star catalogs, image servers, and ITC calculations will be unavailable. Services at Gemini North should not be affected.

Gemini North January NIFS and laser access cancelled

The repair of the Gemini North laser system is proceeding but insufficient progress has been made to offer the laser this month. Because all but one NIFS program requires the laser, this also means we will not be doing the NIFS/NIRI swap this month, as previously planned. NIRI will remain on the telescope and NIFS will not be available. We remain optimistic that we will be on-line for the planned February NIFS+LGS run. Updates will be posted.

Guiding Options

Natural Seeing (Non-Adaptive Optics) Guided Observations:

NIRI standalone (i.e., without AO) requires the use of a peripheral wavefront sensor for both imaging and spectroscopy. PWFS2 is preferred over PWFS1, as it can be used on fainter guide stars, can run at a higher frequency for a given guide star, works better under windy and cloudy conditions, and is smaller and thus vignettes less of the field of view.

f/6 imaging: PWFS2 guide star should be located >5' from the target

Delay to Gemini North NIFS Laser Run

The Gemini North laser system has developed a hardware fault. We are working on a repair which is proceeding quite well but the final prognosis is still not known. January's NIFS+LGS run is delayed and shortened, and may even have to be cancelled. We are optimistic that we will be on-line for the planned February NIFS+LGS run. Updates will be posted.

The dwarf host galaxy was imaged, and spectroscopy performed, using the Gemini Multi-Object Spectrograph (GMOS) on the Gemini North telescope on Maunakea in Hawai'i. Data was obtained on October 24-25 and November 2, 2016. Image Credit: Gemini Observatory/AURA/NSF/NRC.

OT Details for Flamingos-2

The FLAMINGOS-2 team strongly recommends that PIs read this section and also that they start from the automatically-generated OT templates for FLAMINGOS-2 OT library when preparing F2 observations. The library contains detailed instructions for customising the template observations: changing targets, standard stars, slit widths, etc. This web page is intended to explain the various OT components in depth:


Observation Preparation

Observations with the TEXES instrument are taken somewhat differently than those of the regular Gemini instruments. The OT setup for TEXES observations are relatively simple and are used only for two purposes: first, they define the target and the guide star; second, they indicate various basic items of the TEXES configuration (cross-disperser, total requested length of the observation, slit orientation, and central wavelength).

This page guides you through the main steps and considerations for configuring TEXES observations in the Observing Tool:
