What is the meaning of file or object names like 9832a or 0012b?
I’m not sure. My guess is that the first two digits are the year the image was made. The second two either indicate the week or the number, i.e., 9832a was taken in 1998. Either it was taken in the 32nd week of 1998 or it was the 32nd image taken or released in 1998. The highest number I have found is 9943a, so I can’t tell. Regarding the “a” or “b”, those are multiple images of the same object, i.e., 9943c is the third image of the same object imaged in 9943a and 9943b. The numbers are not astronomical catalog numbers! Anytime where the file name is an astronomical catalog number I included the catalog, e.g., M81 or NGC1512.
