Demystifying Carleson Frames

We study spanning properties of Carleson systems and prove a recent conjecture on frame subsequences of Carleson frames.

In particular, we show that if $\{T^k\varphi\}_{k=0}^\infty$ is a Carleson frame, then every subsequence of the form $\{T^{Nk+j_k}\varphi\}_{k=0}^\infty$ where $N\in\mathbb{N}$ and $0 \leq j_k < N$ is also a frame.
