Introduction

This page contains tutorials to guide ALMA users through some common types of data imaging and analysis using CASA with example ALMA datasets. Here are some links to get started:

Basic Imaging and Analysis

ALMA data are delivered to users with calibrations applied and they are ready for imaging. The following "First Look" tutorials provide short examples of common next steps a user may take with their calibrated data. These guides use an example ALMA observation of TW Hydra.

Older versions of these guides are archived here: ALMA First Look

Advanced Imaging

The following are the portions of the End to End guides that cover special imaging topics. The full End to End guides with manual calibration are listed further down this page:

Special Topics

- relevant for data from Cycles 0, 1, and 2
- Also see: Guide To Simulating ALMA Data

End to End Guides (Manual Calibration)

These guides are useful tools for those who would like to learn the process of calibration and imaging in detail. They use publicly-available ALMA Science Verification data that illustrate several different ALMA capabilities. The links below lead to overview pages for each observation. The guides themselves are linked from the overview pages.
