+Shifted Bessel transmissions to match Landolt magnitude system.
+(see calibration note, N. Reynault, 2005)
+
+ (*) We took Bessel transmissions (divided by lambda 
+     with respect to the Bessel (1990) original paper)
+
+ (*) The filters where shifted bluewards by the following amount
+     in order to match the Landolt system well. (see the calib note
+     in notes/calib for an explanation of the whole schmoll).
+
+        U shift: +76.8 dilatation of 0.93 (+)
+        B shift: -41 A
+        V shift: -27 A
+        R shift: -21 A
+        I shift: -25 A
+
+ (+) Using U-B B-V diagram of Landolt stars compared with synthetic ones.
+     The filter obtained is thiner than the orginal one by a factor of 0.93
