FILTERS: * Added two filters to the Filter database G.??stlin purchased two blue narrow band filters (#136 #137), both 100mm diameter. The filters have been stored with the other filters and Pedro has made holders for these two. The throughput was measured using ALFOSC and the results are available from the www-page

ALFOSC *Add SDSS filters to the ETC. Also created a throughput plot for ALFOSC standard UBVRi vs SDSS ugriz-filters. The plot shows the measured throughput multiplied by the CCD QE curve. (http://www.not.iac.es/instruments/alfosc/ALFOSCstdfilt.png)

*Easyflat update: The plan is to add "Flat Combine" to EasyFlat. The idea is to create a pipeline masterflat, which can be used for monitoring flatfields and quick look postprocessing purposes.
