Overview

Data Description

You will use the now-familiar NGC 3256 Band 3 or TW Hydra Band 7 Science Verification data.

Recommended Approach

Continuum Self Calibration

File:Basic selfcal.py

Continuum-to-Line Self Calibration

Self-calibration can also be used to improve your spectral line imaging.
