资源简介：
Pre-processed data from three epochs of observations with NIRC2 at the W.M. Keck II telescope. Each epoch is processed with a flat correction, bad pixel removal, and background removal (via high-pass filter). The subsequent data are co-registered and aligned to the center of the frame before cropping. The crop includes the inner 200 pixels, which corresponds to a maximum angular separation of 1 arcsecond at the edge of the frame. The parallactic angles are provided, too, calculated from the FITS headers including instrumental effects.
