I'm hoping to create seasonal lists for the Herschel II program, similar to what's already been done for the Herschel 400. I've figured out in my Excel document which objects should go in which lists based on the RA and DEC but I wanted to reach out about the best way to do this without going through 400 objects individually and assigning them to a list. Is there a better way? I really enjoy having them separated and working through them by season as opposed to seeing all unseen objects all the time when I have a huge list highlighted. Thanks!
