Problems:
Something is wrong with the CuHeAr lamp and we had to use another one. Again we had problems with the display of the slit on ds9 (at the center of the image the slit dissapeared). After several tests the conclusion was that there is some kind of stain at the window of the instrument that somehow blocks the light. We had to use the 3pxB slit were the effect of the stain seems to be less. We started the observations around 2 am and lost more than 4 hours of observations. We also had to restart the system because it froze almost at the end of the acquisition of the spectrum.
