The filters marked with an asterisk in
Table B have been scanned in October,
1994. No lightleaks were found, except for the [OI] 
6306 filter
(see Fig. 18).
We plan to scan the rest of the interference filters in the
first half of 1995. Many filters are already old, which means in
particular that
their edges are not as smooth as they could be. To
prevent stray light coming in through the edges, especially on INT-PF,
some blocking off of the edges before observing is advisable.
Finally, remember that what you measure is the transmission of the
filter convolved with the CCD response (see Fig 6).
Table 17 gives the standard colour terms for the TEK2 chip at prime focus; this information can also be found in the information browsers at La Palma and Cambridge and in the LPINFO system on the Cambridge VAX GXVG. See also Section 4.8.
