At the beginning of the night I noted some problems with the guider:
1) The orientation in N-S and E-W are rotated.
2) The position of the fiber changed in the guider: (291, 248) to (327, 274)
Probably due to these problems appeared another more important problem:
3) The corrections of the guider were wrong, so it was not possible at first instance to guide the targets.
Humberto Orrego, David Rojas and I inspected the situation, after checking some possibilities we found that changing the symbol (positive to negative) in the GUI: Mode - Intensity Centrod - gain [ms/pixel], it is possible to guide the star with the guider. Using this solution it was possible to continue with the observations, but the orientation N-S and E-W (1) and the position of the fiber (2) in the guider are still an issue. We do not know yet the origin of these problems, for the moment we are observing.
