I reviewed the missing manual, the data standards page: https://data.humantumoratlas.org/standard/imaging, and the HTAN Image Ingress documentation at: https://docs.google.com/document/d/1tK24SA9FLmYmqc8JC2C325dqKF-cabyJqsNLQDGtYyU/edit?tab=t.0#heading=h.b6j67xcu50c2. And, I could not find any information regarding the data elements required within the OME-TIFF headers for Level 2 Imaging Data. These requirements were previously defined in the Level 2 RFC: https://docs.google.com/document/d/1PtNubjp5Kz2E5qrvxVPZEYNLuL13Z-zCHl4Yb6rkTfA/edit?tab=t.0#heading=h.dv1uq7tt9axr
