资源简介:
This data set contains images of Kreutz sungrazing comets that were obtained by the Solar and Heliospheric Observatory (SOHO) spacecraft from 1996-2005. Images have been processed by subtracting a bias, correcting for vignetting, and normalizing by the exposure time. A median of four neighboring images is then subtracted to remove the background. The resulting image has units of data number (DN) per second. A 41x41 pixel array centered on the comet has been extracted for archiving.
