Light Curve Generator and transformed observations

Hi,

The Guide to CCD/CMOS Photometry talks suggests comparing data to that of other observers as a form of self assessment.  It encourages the use of the Light Curve Generator to access the comparison data.  I'm working from transformed observations of my own and I don't see a way to filter the LCG to return only transformed observations.  I can click onto individual observations to see if individual data points have been transformed, typically they are not.  

Is there a way with the LCG to query the database to return only observations that have been transformed to the standard system?  If not, is there another tool that does this?

Thanks,
