tokens: ACKNOWLEDGEMENTS The authors thank the anonymous referee for constructive feedback that improved the manuscript. We wish to sincerely thank all the National Radio Astronomy Observatory, SMA, JCMT, and IRAM NOEMA staff that supported us during this observing campaign. The authors also offer a special thanks to the IRAM NOEMA Director, Karl-Fredrich Schuster, for granting our NOEMA DDT request. AJT thanks Craig Heinke and Bailey Tetarenko for useful discussions on accretion disc contributions in broad-band spectra of X-ray binaries. AJT is supported by an Natural Sciences and Engineering Research Council of Canada (NSERC) Post-Graduate Doctoral Scholarship (PGSD2-490318-2016). AJT and GRS are supported by NSERC Discovery Grants. JCAMJ is the recipient of an Australian Research Council Future Fellowship (FT140101082). SBM acknowledges support from VICI grant Nr. 639.043.513/520, funded by the Netherlands Organisation for Scientific Research (NWO). TDR acknowledges support from the NWO Veni Fellowship, grant number 639.041.646. DA acknowledges support from the Royal Society. This work is based on observations carried out under project numbers S15DE and D15AB with the IRAM NOEMA Interferometer. IRAM is supported by INSU/CNRS (France), MPG (Germany), and IGN (Spain). The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc. We thank the engineers and staff of the Mullard Radio Astronomy Observatory for maintenance and operation of AMI, which is supported by the Universities of Cambridge and Oxford. The AMI telescope acknowledges support from the European Research Council under grant ERC-2012-StG-307215 LODESTONE. The SMA is a joint project between the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy and Astrophysics, and is funded by the Smithsonian Institution and the Academia Sinica. The JCMT is operated by the East Asian Observatory on behalf of The National Astronomical Observatory of Japan; Academia Sinica Institute of Astronomy and Astrophysics; the Korea Astronomy and Space Science Institute; the Operation, Maintenance and Upgrading Fund for Astronomical Telescopes and Facility Instruments, budgeted from the Ministry of Finance (MoF) of China and administrated by the Chinese Academy of Sciences (CAS), as well as the National Key RD Program of China (No. 2017YFA0402700). Additional funding support is provided by the Science and Technology Facilities Council of the United Kingdom and participating universities in the United Kingdom and Canada. The authors also wish to recognize and acknowledge the very significant cultural role and reverence that the summit of Mauna Kea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain. We acknowledge with thanks the variable star observations from the AAVSO International Database contributed by observers worldwide and used in this research.
