Seeing Where Stars Collide






Gemini Observatory near-infrared image of the globular cluster Liller 1 obtained with the GeMS adaptive optics system on the Gemini South telescope in Chile.

Calibrations

To properly reduce GPI observations one must download the proper calibrations. This document describes how the user can download all types of calibrations from the GSA. The user should read the instructions here on how to access the GSA, these instructions are only details on how to access GPI particular data. 

Discovery Harkens to Early Solar System

Figure 1. Image of HD 115600 showing a bright debris ring viewed nearly edge-on and located just beyond a Pluto-like distance to the star. One or more unseen solar system-like planets are causing the disk center (diamond) to be offset from the star's position (cross).

Observation Preparation with GPI

This section contains instructions for configuring GPI at phase II. It is organised as follows:

GPI Phase II Checks

Purpose

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. 

Background

The Phase II check point of view GPI consists of 4 components as these are driving the Phase II checking.

 

Calibration (GCAL)

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.

GMOS Data Format and Reduction

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.
