This Directory holds information about the filters used in the LAICA 
instrument and was taken from:
http://www.caha.es/CAHA/Instruments/LAICA/manual.html#fil

The LAIWO filters BVRIz are identical in characteristics to the LAICA filter
and thus this following information applies to the LAIWO filters as well, 
although for the LAICA there are more filters which LAIWO does not have.

The following filters are standard LAICA filters.

The file filters_johnson.gif  is the transmission curves for the 
Johnson-like filters, in which LAIWO has BVRI.

The file filters_SDSS.gif is the transmission curves for the SDSS filters,
in which LAIWO has only the z filter. 

The *.txt files are the ASCII version of these transmission curves.

The file Laiwo_Science_CCDs.pdf is the specification sheet for the LAIWO
science CCDs, although this is the 2010 version of it it is similar to the 
2004 version of it that was supplied with the LAIWO instrument.
