Notes on IR Filters:

* Check the ISPI pages [65] to see if the filter is currently in the ISPI Dewar.

The filters listed above have seen recent use in Tololo imagers. There are other filters available. Observers should check with the staff noted below if there is a filter or transmission curve not listed above which would be of interest.

In response to an increasing number of requests, we are starting to place digital versions of the transmission data for some of our filters here. The user should take some care to verify that the filter is valid for the instrument he or she is considering at the time of use in question. The actual filter in use will in general not be the exact filter for which we have transmission data, but rather be one of the same batch. The numbers refer to the CTIO filter ID by which the filter data is archived. In case of doubt, consult with Nicole van der Bliek, Patrice Bouchet, Bob Blum, Brooke Gregory.
