One-dimensional infrared speckle scans of Ross 614 AB were recorded at a wavelength of 2.2 microns, and the three bins corresponding to the three best seeing conditions were further processed by applying a shift-and-add algorithm to the set of images contained within each bin, generating three shift-and-add images with differing shift-and-add point-spread functions. A zero-and-add technique was used to deconvolve the three shift-and-add images in order to obtain parameters corresponding to the separation and the brightness ratio of a two-component model of Ross 614 Ab. Least-squares analysis results reveal a separation of 1.04 arcsec and a brightness ratio of 4.3 for the binary system at this wavelength.
