MakeCatalog currently needs to load a lot of data before starting. In the case of large images, this can easily be felt.

Corresponding source code
This task has been completed as part of a larger process and pushed to the main repo. MakeCatalog can now read the Sky and Sky standard deviation datasets as a single-element-per-tile array. It will also only load datasets that are necessary for the requested columns.
