OPERA DSWx-HLS input dataset DOI.

Hello, I am looking for the specific HLS dataset that is used as input to create the DSWx-HLS product. According to Figure 1.1 in the OPERA Product description document (https://d2pn8kiwq2w21t.cloudfront.net/documents/OPERA_Product_Document.pdf), the input dataset used to create the DSWx-HLS product is HLS v2.

However, I was unable to find a specific citation/DOI for the HLS v2 product in the OPERA documentation.

I assume that the citations/DOIs for the HLSv2 product used as input are as follows according to LP.DAAC(https://lpdaac.usgs.gov/news/release-of-harmonized-landsat-and-sentinel-2-hls-version-20/):

If anybody could point me towards DSWx-HLS documentation that confirms this, that would be greatly appreciated. Thank you!
