It is possible to change the angle but possibly the x,z pos will not come out right.Since the relative positoin and the angle are not decoupled but describe by only two parameters refdist and refangle You might try to set "set_param t2 refangl 2.36 (i.e 8.31-5.95) and check the x,z pos. I would guess that for acceptance it is more important with the proper position than with a correct rotation angle. It is clearly something to take care of (in the future). Flemming ----- Original Message ----- From: Pawel Staszel To: brahms-dev-l@bnl.gov Sent: Tuesday, January 23, 2001 11:22 AM Subject: fs geometry Hi. I have question that concerns forward spectrometer setup under gbrahms, so I guess it is mainly addressed to Flemming. The rotation angles of D1, T1, D2, T2 and H1 used in data analysis for 4 deg runs are -4, -5.95, -5.95, -8.31 and -7.85, respectively. Using gbrahms one can not reproduced this setup. The closest setup I can use now is -4, -5.95, -5.95, -7.85, -7.85. Is it so? If not what one can do to get desired configuration?
