  The New Vacuum Solar Telescope (NVST) has been releasing its novel winged Ha
data (WHD) since April 2021, namely the Ha imaging spectroscopic data. Compared
with the prior released version, the new data are further co-aligned among the
off-band images and packaged into a standard solar physics community format. In
this study, we illustrate the alignment algorithm used by the novel WHD, which
is mainly based on the optical flow method to obtain the translation offset
between the winged images. To quantitatively evaluate the alignment results of
two images with different similarities, we calculate the alignment accuracies
between the images of different off-band and line center, respectively. The
result shows that our alignment algorithm could reach up to the accuracy of
about 0.1 "when the off-band of winged image is lower than 0.6 \.A. In
addition, we introduce the final product of the WHD in detail, which can
provide convenience for the solar physicists to use high-resolution H{\alpha}
imaging spectroscopic data of NVST.
