Galactic Herding: New Image Brings Galaxy Diversity to Life

Gemini North is now accepting proposals for the first cycle of the Fast Turnaround (FT) pilot program

Gemini North is now accepting proposals for the first cycle of the Fast Turnaround (FT) pilot program. Here, we give information specific to this proposal cycle. Please see the other FT pages - particularly the rules - for general information about the program.

Semester 2015A

This page provides instructions for completing Phase II Science Programs for all Gemini North and Gemini South instruments. It includes submission details and notes of any procedural changes. Please read this page carefully!



Sensitivity Table (Imaging)

This page presents results from using the GMOS Integration Time Calculator (ITC). The table lists the estimated brightnesses of point sources and uniform surface brightness sources that give a signal-to-noise ratio (S/N) of 5 in a one-hour integration.

Defining a N&S Observation

In this section we outline a few definitions and features of a GMOS Nod & Shuffle observation.

Cycle: A Nod & Shuffle cycle is defined as the smallest useful quantity in the Nod & Shuffle exposure. In theory, this is one exposure in the target position and one exposure in the sky position.

Announcement of Opportunity for new Large and Long Programs

Gemini Observatory announces an opportunity for new Large and Long Programs. Eligible PIs are invited to propose scientific investigations to begin observation in the 2015B semester. Letters of Intent are due February 2 2015, and completed proposals are due March 31 2015.  Details and requirements are available in the Announcement of Opportunity.

GNIRS in the Observing Tool

The GNIRS team strongly recommends that users start from the automatically-generated OT templates and the GNIRS OT library when preparing GNIRS observations. The library contains detailed instructions for customising the template observations: changing targets, standard stars, slit widths, wavelengths, etc. This web page is intended to explain the various OT components in more depth:
