Since identification of lensed systems are difficult, I hope that SED of lensed systems would provide better picture.


This is the regions used in determining SED

All SED plots are in x axis: wavelengths in nm y axis: flux , note: in log scale


system A: they are in good agreement of each other , no changes to glafic model required

System B, Generally in good agreement

B4 is obviously the outlier (right next to the Nose), However, since it is every close the BCG, which contaminate heavily towards longer wavelengths.

B3 stands in midway between B1 and B2 groups, it doesnot exhibit increase in flux at 814 filter.

From this, I will try to use B1,B2 and B5 as constrains.

System C: all in good agreements, no changes required

System J, near System A, J1 and J2 shows similar SED, however we don't have spec-z

SED for other systems
