The Molecules with ALMA at Planet-forming Scales Large Program (MAPS LP) surveyed the chemical structures of five protoplanetary disks across more than 40 different spectral lines at high angular resolution (0.″15 and 0.″30 beams for Bands 6 and 3, respectively) and sensitivity (spanning 0.3–1.3 mJy beam−1 and 0.4–1.9 mJy beam−1 for Bands 6 and 3, respectively). In this article, we describe the multistage workflow—built around the CASA tclean image deconvolution procedure—that we used to… Expand

TLDR
This work has shown that molecular line observations are an essential complement to high resolution continuum data when studying the planet formation environment, the protoplanetary disk, but unlike continuum observations, observations of line emission requires a much higher sensitivity for them to be robustly detected.
