Abstract

Using the results of photometry applied to speckle image reconstructions of the triple stellar system LHS1070 in the near infrared, we compare quantitatively the performance of shift-and-add and bispectrum image reconstruction methods and find that comparable results can be obtained. It is also found that, within this regime, compensation of the bispectrum transfer function is necessary to prevent telescope aberrations from appearing within bispectrum image reconstructions. The effective point-spread functions of these aberrations have been calculated with phase data obtained from the stellar calibration source.
