Description
Thousands of observations of the well-studied Galaxy and Mass Assem-
bly (GAMA) fields, GAMA9 and GAMA23, have been conducted with the
MWA (Murchinson Widefield Array) radio telescope for the MWA Interestingly
Deep Astrophysical Survey (MIDAS) and the GAMA23 OverwheLming Deep
(GOLD) survey. Here we present deep images of the GAMA9 and GAMA23
fields centered at a frequency of 215.68 MHz with a bandwidth of 30.72 MHz,
produced from these observations obtaining an RMS below 1 mJy/beam. These
deep field images will assist in determining source counts to produce low-frequency
radio luminosity functions that can be used to analyse radio galaxy evolution.
In addition, we provide a detailed description of the automated Deep Imaging
Pipeline (DIP) that enabled the creation of these images. DIP was adapted from
the pipeline used in the GaLactic and Extragalactic All-sky MWA X (GLEAM-
X) survey with improvements in the cleaning for deep imaging and automation
to allow large batch processing with minimal user input.
