Query: Uniform error estimates for nonequispaced fast Fourier transforms   In this paper, we study the error behavior of the nonequispaced fast Fourier
transform (NFFT). This approximate algorithm is mainly based on the convenient
choice of a compactly supported window function. So far, various window
functions have been used and new window functions have recently been proposed.
We present novel error estimates for NFFT with compactly supported, continuous
window functions and derive rules for convenient choice from the parameters
involved in NFFT. The error constant of a window function depends mainly on the
oversampling factor and the truncation parameter.
