Tilt + misalignment behaves strange in MAD-X PTC

[tpersson]

It looks to be like the misalignment is applied in the tilted frame and is therefore moving the magnet in the wrong direction. I attach an example to illustrate:

FASER : SEQUENCE, L = 10;
b1:sbend, angle=138/180.0pi, HGAP=0.0258,e1=0/180.0pi, e2= 0/180.0pi,FINT=0.5 ,TILT=1.0pi, at=5,l=1;
endsequence;

beam;
use, sequence=faser;

eoption, add=true;
select, flag=error, clear=true;
select, flag=error, class=b1;
ealign, dx= 0.001, dy= 0.00, ds=0.00,dphi=0.00, dtheta=0.00, dpsi=0.00;

select, flag=twiss, column=name,s,x,px,y, py;
twiss, betx=1, bety=1, x=-0.000, file="mytwiss.dat";

ptc_create_universe;
ptc_create_layout, model=2, method=6,nst=10, exact;
ptc_align;
ptc_start, x=0.000;
ptc_observe, place=b1;
ptc_track, icase=5, element_by_element, dump, file="track.simple", ffile=1, onetable, maxaper={100.0, 100.0, 100.0, 100.0, 100.0, 100.0};
ptc_twiss, file="twiss.ptc.simple",betx=1,bety=1,betz=1;
ptc_track_end;

ptc_end;
