We started doing two dark scans. We tried to point using 3C84 but the source was far from the center -38,-20 arcsec. After discussions with Juan Peñalver we decided to use nasmyth offset computed by Nicolas on run 9: offsets -18.8 -5 /sys nasmyth, However, this did not solve either the problem. We switched to Mars but encountered the same problem. Finally, we found that the problem was related to a wrong reference kidpar - we corrected this and everything started work fine. |
