I guess you are referring to the measured (spectrally resolved) 
reflectance and transmittance data in the International Glazing DataBase 
(IGDB) that is used by Optics? I have no idea why, but the data comes as 
a MS Access database file. It is possible to open such files using 
various open source tools, e.g. I managed to load it into Openoffice. 
The database contains one table called GlazingProperties which is 
probably the one to look for.

Actually I wonder whether one should hint the developers at migrating 
that database to some SQL. That would not only make it possible to 
connect other tools easily, but also would allow the maintainers to 
update records of their database without redistributing the whole huge 
download. That is actually what network connectivity of databases was 
made for.

Cheers, Lars.
