• 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

• 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 3.4 The latest version is 4.2.
    • 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
