Suppression of every plots if required

[sylvielsstfr]

It appears that some plot are sent to output even if the parameters say not to do so.
It prevents running on batch machines.

The output is like this:

MAIN_ID RA DEC RA_PREC DEC_PREC COO_ERR_MAJA COO_ERR_MINA COO_ERR_ANGLE COO_QUAL ... PLX_QUAL PLX_BIBCODE PMRA PMDEC PM_ERR_MAJA PM_ERR_MINA PM_ERR_ANGLE Z_VALUE SCRIPT_NUMBER_ID
