Basic Imaging and Analysis
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.

End to End Guides (Manual Calibration)
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.

Discusses full calibration of 12m interferometry Band 9 (high frequency) data, including inspection of the data for flagging, and plotms commands to recreate plots typically included in a QA2 weblog. Also discusses imaging of mosaic data, including self-calibration and generation of image cubes and moment maps.

Special Topics
- - relevant for data from Cycles 0, 1, and 2
- - Also see: Guide To Simulating ALMA Data
Legacy Guides
- - Last checked in CASA 4.2
- - Helpful hints for downloading the data
- - Imaging, self-calibration, and image analysis
- Example data calibration scripts used for Cycle 0 data (CASA 3.4):
- File:TDM.example.ms.scriptForCalibration.py: TDM (128 channels/spw)
- File:FDM.example.ms.scriptForCalibration.py: FDM (3840 channels/spw)
- Updating a script to work with CASA 4.2: Update 3.4 scripts to 4.2 or later.
Resources
