Hi, thank you for reaching out.
Please note that there are various DECam programs besides the DESI Legacy Surveys program, i.e. it's not safe to assume that any particular PROP ID would be included in a DESI Legacy Survey data release.
For questions regarding the content of LS DR9, please refer to the LS team. Information can be found at https://www.legacysurvey.org/contact/
Finally, regarding your question about "a paper", I'm not sure what you are asking. A science paper? The observational proposal? Can you please clarify?
