TL;DR: The Lijiang 2.4-meter Telescope (LJT) as mentioned in this paper, the largest common-purpose optical telescope in China, has been available to the worldwide astronomical community since 2008.
Journal ArticleDOI
Spectral and Imaging Observations of a Current Sheet Region in a Small-scale Magnetic Reconnection Event
TL;DR: In this paper, the authors reported a possible current sheet region associated with a small-scale magnetic reconnection event by using the spectral and imaging observations of the Interface Region Imaging Spectrograph (IRIS) and the magnetograms obtained by the Solar Dynamics Observatory on 2016 August 08.
Proceedings ArticleDOI
A subpixel registration algorithm for low PSNR images
TL;DR: In this article, a fast algorithm for obtaining high-accuracy subpixel translation of low PSNR images is presented, instead of locating the maximum point on the upsampled images or fitting the peak of correlation surface, the proposed algorithm is based on the measurement of centroid on the cross correlation surface by Modified Moment method.
