<div>
<div>This dataset and code supplement accompanies the manuscript submitted to AGU Journal of Geophysical Research: Solid Earth (JGR Solid Earth), <em>Effect of Data-Derived Tomographic Model Uncertainty on Moment Tensor Estimation</em>, by Savvas Marcou et al. It contains the final tomographic models, in both NETCDF format (for visualization), and HDF5 (for performing simulations using Salvus). It also contains event and waveform information for the events used in the tomographic and moment tensor inversion, as well as moment tensor inversion results. For a full description of the contents, consult the README file.</div>

EXACT ALTERNATING SUMS OF ORDERED q-STIRLING NUMBERS
Authors: Himelhoch, Akiva
Type: Preprint
Published: 2026-08-03

<p>This note evaluates, in closed form, the weighted alternating sums T_n^(m)(q) = sum_{k=0}^{n} (-1)^(n-k) q^(m(n-k)) S°[n,k] of the ordered q-Stirling numbers S°[n,k] of Sagan and Swanson, for every integer m ≥ 1. The case m = 2 gives T_n^(2) = (1-q)(1+q)^n + q^(n+1), whose coefficients are the signed ballot numbers C(n,j) - C(n,j-1); this proves Conjecture 7.9 of Sagan and Swanson (q-Stirling numbers in type B, European J. Combin. 118 (2024)) and refines their congruence T_n^(m) ≡ 1 (mod q^m - q). The proofs are elementary, using only a two-parameter recurrence and induction.</p>
