Overview

This guide describes how to combine the 7m and 12m interferometric data and then how to feather the resulting image with the total power TP image. All of the data for this SV project can be found at https://almascience.nrao.edu/alma-data/science-verification. In order to run this guide you will need to:

• Either run the 7m casaguide M100_Band3_ACA_4.3 to obtain the final 7m fully calibrated data or download the fully calibrated data: (i.e. M100_Band3_7m_CalibratedData.tgz)

• Either download the new RawUnCalibrated data for the 12m-array and run the new calibration script or download the fully calibrated data (i.e. M100_Band3_12m_CalibratedData.tgz). Note that while these are the same data that were released previously, the data reduction path has been updated to current best practices and starts from the raw data files called ASDMs (ALMA Science Data Model). Do not use the previously released uncalibrated or calibrated data.

• Either run the M100_Band3_SingleDish_4.3 guide to calibrate and image the Total Power data or download the final image (i.e. M100_TP_Image.tgz)
