*** FINAL CALIBRATION VALUES: ***

sc = (4.911e-07 +/- 8.51e-08) * ((bbcbb) - (-303.8 +/-  398.8))

  with GL =  0.74 +/-  2.56

The best scaler that fits the data well is "bbcbb". The GL value  (GL =  0.74 +/-  2.56) seems reasonable, however the error is large relative to the actual value.
I think, it is reasonable to fix the GL to 0.5. Below is the result fixing GL=0.5.

Fig: SC measured  vs fit for bbcbb for GL =0.5 (fixed).

The best alternative to the "bbcbb" would be "vpdw", however, it doesn't describe the data well as "bbcbb" does.
