When running ODL FBP example, like the example for 2D parallell beam acquisition, the resulting FBP reconstruction is off by a (large) constant factor. In the example, phantom values range from 0 to 1 whereas FBP reconstruction values range from 0 to 0.002.
FBP should not behave like this, and especially not in 2D parallell beam acquisition setting where it is theoretically exact.
