  Written in Python and utilising ParselTongue to interface with the
Astronomical Image Processing System (AIPS), the e-MERLIN data reduction
pipeline is intended to automate the procedures required in processing and
calibrating radio astronomy data from the e-MERLIN correlator. Driven by a
plain text file of input parameters, the pipeline is modular and can be run in
stages by the user, depending on requirements. The software includes options to
load raw data, average in time and/or frequency, flag known sources of
interference, flag more comprehensively with SERPent, carry out some or all of
the calibration procedures including self-calibration), and image in either
normal or wide-field mode. It also optionally produces a number of useful
diagnostic plots at various stages so that the quality of the data can be
assessed. The software is available for download from the e-MERLIN website or
via Github.
