Introduction

This page contains tutorials to guide ALMA users through some common types of data imaging and analysis using CASA with example ALMA datasets.

CARTA

Guides that have been updated to demonstrate the CARTA image viewer will include this statement near the top:

This guide features CARTA, the “Cube Analysis and Rendering Tool for Astronomy,” which is the new NRAO visualization tool for images and cubes. The CASA viewer (imview) has not been maintained for a few years and will be removed from future versions of CASA. We strongly recommend using CARTA, as it provides a much more efficient, stable, and feature rich user experience. A comparison of the CASA viewer and CARTA, as well as instructions on how to use CARTA at NRAO, is provided in the CARTA section of the CASA docs.

First Look (TW Hydra)

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

Imaging

Manual Calibration and Imaging

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.

  • AntennaeBand7 (NGC 4038/4039)
  • Band 7 (0.87 mm)
  • North and South mosaics

Protostellar Cluster IRAS16293-2422

  • M100_Band3
  • Band 3 (?? mm)
  • Total Power (Single Dish) calibration and imaging
  • Combining 12m-array, 7m-array, and Total Power data

3C286 Full Polarization

Sunspot

  • Sunspot_Band6
  • Band 6 (1.25mm)
  • Solar observing techniques
  • Calibration and imaging
  • Helper scripts

Simulation

Legacy Guides

The following ALMA guides and scripts using Science Verification data have been validated for older versions of CASA, and will not continue to be updated for new CASA releases.

Cycle 0

You can also get a look at example data calibration scripts used for Cycle 0 data at the following links. These were written for CASA version 3.4.
