Description:
    Catalogue containing solar X-ray bursts measured by the Danish Wide
    Angle Telescope for Cosmic Hard X-Rays (WATCH) experiment aboard the
    Russian satellite GRANAT in the deca-keV energy range. Table 1 lists
    the periods during which solar observations with WATCH are available
    (WATCH ON-TIME) and where the bursts listed in the catalogue have been
    observed.

Note (1): Converted to the time accumulation of the bin.

Note (2): '1' for yes,
          '0' for no,
          'n' implies that some particle noise is observed in the high-energy
               channel, but not at the peak time of the burst.
Note (3): 'd' for yes, '0' for no.

Note (4): 'o' for yes, '0' for no.

Note (5): '0' for no association.

Note (6): 'N' for none, 'ng' implies that no GOES data exists.

Note (7): '1' for yes, '0' for no.
