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:

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.

Gemini Instrument Feasibility Study

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:

Gemini IRAF 1.13 available in recent Ureka 1.5.1 release

Version 1.13 of the Gemini IRAF package is now available in the latest version of Ureka, 1.5.1, released last month (http://ssb.stsci.edu/ureka).

Star Pair’s Dusty Disk Shines Light on Planet Formation

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.
