Filters

The Z (maybe better called Y; see Hillenbrand et al. 2002, PASP, 114, 708) and HeI$_{\rm B}$2.059$\mu$m filters originally ordered in 1999 arrived and were installed. Also, four filters ordered by Göran Östlin arrived and were installed. Three of these filters were substitutes of filters that arrived earlier but were found to be faulty. These ``Östlin'' filters are available for general use.
