General Remarks

The filters marked with an asterisc in Table 2 have been scanned in October, 1994. No lightleaks were found, except for the [OI] 6306 filter We plan to scan the rest of the interference filters in the first half of 1995. Many filters are already old, which means that especially their edges are not as smooth as they could possibly be. To prevent stray light coming in through the edges, especially on INT-PF, be sure to tape off the edges before observing. Also, when calculating filter response curves: be sure that you also take into account the relative transmission of the CCD.
