movie.py: center of mass evaluation #10

Closed PaoloSuin closed 3 years ago

PaoloSuin commented 3 years ago

There's a compilation error in line 302 of movie.py tool, inside function corretctCM: the y coordinate of the core centre of mass is subtracted to x coordinates 


    def correctCM(self, boxsize, pos):
        xcm = 0.0
        ycm = 0.0
        if (self.cm_mode=='core'):
            xcm = pos[0]
            ycm = pos[1]
            if (self.generate_binary!=2): # data from petar.data.process already remove c.m. from core center
                self.x = self.x-ycm   <<<<<
                self.y = self.y-ycm

Thank you for pointing this out! Now I have fixed it.
