1. Overview

This is a tutorial for the reduction of Flamingos 2 longslit spectroscopic data with DRAGONS.

Flamingos 2 is a near-IR spectrograph offering imagining, longslit spectroscopy, and multi-object spectroscopy (MOS). This tutorial focuses on the longslit spectroscopy.

For Flamingos 2 imaging, see Flamingos 2 Imaging Data Reduction Tutorial.

In this tutorial, you will be able to run the examples yourself and experiment with the process. The tutorial comes with downloadable data packages that contains all the data you need to run the examples presented. Instructions on where to get that package and how to set things up are given in Downloading tutorial datasets.

The Flamingos 2 longslit tutorial series contains three scientific examples covering all three grating settings.

The reduction can be done in two different ways:

• From the terminal using the command line.

• From Python using the DRAGONS classes and functions.

We show how to run the same reduction using both methods.

The tutorials are:

• JH grating

• HK grating

• K-band R3K grating

See the DRAGONS Installation Instructions to install the software if you have not already.

Tip

If you are using the tutorials to guide you through the reduction of your own data and you encounter a problem, please review the Tips and Tricks and Issues and Limitations sections. They may contain the solution to your problem.
