ALMAguides

• How to use these CASA Tutorials

The following ALMA science verification guides have been validated for CASA version 4.3. They should also work for CASA version 4.4, and they will be validated for version 4.4 soon.

• Guides for reducing ALMA Science Verification data using CASA 4.3
  • The links below lead to overview pages for each science verification observation. The guides themselves are linked from the overview pages. These guides are a useful tools for those who would like to learn the process of calibration and imaging in detail.
  • TWHydraBand7: The protoplanetary disk source TW Hya at Band 7 (0.87 mm)
  • NGC3256Band3: The galaxy merger NGC 3256 at Band 3 (3 mm)
  • AntennaeBand7: Mosaic of the galaxy merger NGC 4038/4039 (Antennae) at Band 7 (0.87 mm)
  • IRAS16293Band9: Mosaic of the protostellar cluster IRAS16293-2422 at Band 9 (0.45 mm)
  • File:BR1202 SV Band7 Calibration notes.pdf: Supplemental notes on the calibration of Science Verification target BR1202-0725 in CASA 3.3
  • ALMA2014_LBC_SVDATA: Imaging scripts and details for the 2014 ALMA Long Baseline Campaign science verification data for Juno, Mira, HL Tau, and SDP.81.

• A Guide to Processing ALMA Data for Cycle 0
  • This page takes you through the steps of processing Cycle 0 data from the ALMA data archive. The guide describes some helpful hints for downloading the data, and describes the process all the way through imaging and self-calibration, and image analysis.
  • 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.
    • TDM (128 channels/spw) File:TDM.example.ms.scriptForCalibration.py
    • FDM (3840 channels/spw) File:FDM.example.ms.scriptForCalibration.py
    • If you need to update 3.4 scripts to 4.2, see more information here
