[Issues] Filter names cause problems with filenames

[Jan Snigula]

Hi all,

We just noticed, that the names for the ESO medium and narrow band  
width filters cause problems with the resulting filenames. The filter  
MB#549/16 (or NB#OIII/2) produce filenames like Cal-SPHLEPS-WFI------- 
MB#549/16-ccd52-Mas-Dome- 
Flat-54083.4862414-840a714988cbd345a6ef955c7c3271e940b146cc.fits that  
cannot be stored to the dataserver.

Cheers,

Jan
