The proposed model has the modulations of the two Pr atoms within one unit cell in phase. This implies a specific phase shift of the single symmetry independent Pr modulation in the present description. 
In the present description, the phase origin for the modulation is chosen at the inversion centre along x4. This initial phase choice is different from the one in the publication.
