apodize\ˈa-pə-ˌdīz\ play transitive verb,
apodizingAmplitude and phase errors tend to increase at high spatial frequencies, so we weighted the data with a function that is 1 at a frequency of 0 and falls to 0 at a spatial frequency of 2.8 cycles per arc second. A similar function was used to apodize the visibilities before reconstructing the images. — R. R. Howell et al., Science, 4 Oct. 1985
