Dear colleagues,

I am writing to you regarding your abstracts submitted to WG1: Structure Functions and Parton Densities at DIS2022 in Santiago de Compostela. As you may be aware, being one of the first in person conferences in a long time, we have received an extraordinary number of abstract submissions. As a result, we are writing to ask you if it might be possible to merge two of the abstracts submitted by yourselves on behalf of the nCTEQ collaboration into one talk. The abstracts we refer to are "Constraining the nuclear gluon PDF with heavy quark production data" (abstract number 19 submitted by Pit Duwentaester) and "nPDF Analysis with Neutrino DIS Data" (abstract number 50 submitted by Khoirul Faiq Muzakkaand and Karol Kovarik). Please let us know if this is would be fine for you as the authors as soon as possible and thanks in advance for your understanding.

Many thanks,

Tom Cridge on behalf of the WG1 conveners (Tom, Barak, Klaus)
