Description:
    We present the results of an optical photometric survey of 616
    irregular variables. The targets were selected among objects
    classified as L, L:, I, I:, IS and IS: in the General Catalogue of
    Variable Stars and New Catalogue of Suspected Variable Stars.

Note (1): *: Nights without calibration sequences (see discussion in the paper)
          1: Averaged values of magnitude and colours. Object is a Mira variable
          2: Averaged values of magnitude and colours. Object is a cataclysmic
              variable
          3: 10 arcsec optical pair. Possible contamination
          4: Classified as probable Herbig Ae/Be object in Gregorio-Hetem et al.
              (1992AJ....103..549G)
          5: 10 arcsec optical pair (~2mag weaker) included in the diaphragm
          6: Averaged values of magnitude and colours. Object is a symbiotic u
              star
          7: Suggested as Cepheid variable by Booth & Charles
              (1982MNRAS.201p..25B)
          8: Object is a RV Tauri variable
          9: Optical pair (~2mag weaker) included in the diaphragm
         10: Quoted as suspected of cataclysmic variable in Vogt & Bateson
              (1982A&AS...48..383V) and Downes & Shara (1993, Cat. <V/79>)
         11: Quoted as suspected of cataclysmic variable of Z Cam type in the
              GCVS4 (kholopov et al. 1987, Cat. <II/139>)
         12: Classified as T Tauri star in Torres et al. (1995AJ....109.2146T)
         13: Carbon star
         14: Optical pair. The two stars were included in the diaphragm

         19: Object is a RR Lyrae variable
