Continuum-subtracted and non-continuum-subtracted measurement sets ("[SOURCE]_[RECEIVER]_[SIDEBAND].ms.[contsub].tar.gz"), line image cubes ("[SOURCE]_[RECEIVER]_[SIDEBAND]_[SPW]_cube.fits"), and continuum images ("[SOURCE]_[FREQ]_continuum.fits") associated with Law et al., 2024, "A Wideband Chemical Survey of Massive Star-forming Regions at Subarcsecond Resolution with the Submillimeter Array," accepted to ApJS. The measurement sets are listed according to receiver (RX240, RX345) and sideband (LS, US), while the line image cubes are further sub-divided into four separate spectral windows (0-3) for each receiver and sideband combination. All images are contained in the per-source directories ("[SOURCE]_images.tar.gz"). The raw data are available on the SMA archive via project codes 2018B-S023 and 2019A-S006 (PI: C. Law).
