No single-dish continuum data

- Check that the central hub is opened (STSA), and that the table is in position (RECEIVER user).
- If both are correct, it means the pointing is bad. Check the antenna time (UT program on the POINTING micro).
- If bad, reset it using the set_time program on the POINTING micro.
- Reload the pointing constants (by a SET$\backslash$OBSERVE command), and check the pointing.
- If still bad, reinitialize the antenna, and check the pointing.
