Galaxy Groups

[theskyhound]

Hello Carles,

Thanks for bringing this up. The first thing to do is to make sure that the galaxy group isn't in the latest database. To do that, open it in the atlas and have a look for it. You may need to increase the magnitude limit for galaxy groups. Be sure to check that your supplemental database object is at the right position, using something like SIMBAD or NED, if you don't see any galaxies at that location. If it does show up in the regular database, then replace the supplemental database object with the regular database object in your lists. Its more difficult if you have logs for it. You may need to copy the log data to a temporary text file and then create a new log entry for the object from the regular database using that previous info.

As far as calculating the visibility for supplemental database objects, there isn't a good way to do that. There is not enough information included. The presumption is that supplemental database objects are there for very rare cases where the object isn't in the database. Be sure to report the missing object to me, providing the designation and RA/Dec, so I can make sure to add it in the future.
