Data Processing

AIPS	The NRAO Astronomical Image Processing System (AIPS ) is a software package for interactive (and, optionally, batch) calibration and editing of radio interferometric data and for the calibration, construction, display and analysis of astronomical images made from those data using Fourier synthesis methods.
AIPS Cookbook	The AIPS CookBook is intended to help beginning users of the NRAO Astronomical Image Processing System (AIPS) by providing a recipe approach to the most basic AIPS operations.
AIPS VLBA Calibration Pipeline	The VLBA data calibration pipeline processing using the VLBARUN procedure in AIPS.
CASA	The Common Astronomy Software Applications (CASA) package is a C++ data reduction toolset bundled under an iPython interface.
Caltech VLBI Programs	A set of interactive programs developed at Caltech that are used by many VLBA observers for very long baseline synthesis imaging, visualization, and self-calibration.
AIPS and CASA VLBI Tutorials	Very Long Baseline Interferometry (VLBI) Data reduction tutorials in AIPS using VLBA data and in CASA using EVN data.
Post Observing Notes/Issues	Notes on specific issues that affected data quality and/or require particular attention for data processing and interpretation.
