Data Acknowledgement

Proposed acknowledgement (to be tagged to the data collections in archives, on github, on webpages, etc).

ALFALFA observations were obtained from 2005-2012 with the Arecibo Observatory, which operated from 1963 until its untimely collapse in 2020. At the time the data were taken, the Arecibo Observatory was part of the National Astronomy and Ionosphere Center (NAIC), operated by Cornell University under a cooperative agreement with the National Science Foundation (NSF). These data products are the work of the entire ALFALFA collaboration who have contributed to the many aspects of the survey over the years, including generations of students from the Undergraduate ALFALFA Team. Their research was supported by grants from a variety of agencies, including the NSF and the Brinson Foundation. The ALFALFA team is indebted to - and mourns the loss of - survey lead Riccardo Giovanelli, who was an inspiration to us all.

Publications using ALFALFA data should cite Giovanelli et al. (2005) and Haynes et al. (2018), the definitive references for the survey. We also request that you include the following in the acknowledgements section of your publication:
