Luminance filter

Can I upload images using the L filter?  WebOBS does not recognize it.  I understand it's not a photometric filter but it is suggested for use for extremely dim objects like some CVs.  

Curious if I can upload the images somehow and if there is any benefit.  

Thanks,

The data might be useful if you adjust the zero-point to Sloan r' using either the Pan-STARRS catalogue or the more recent ATLAS refcat2 as the source for the comparison star magnitudes.

Hi Henry,

WebObs considers the luminance filter to be a clear filter.  You report it in one of two ways:

- if you use V-band comparison stars, report your magnitudes as CV

- if you use R-band comparison stars, report your magnitudes as CR
