This continuing study of intragroup light in compact groups of galaxies aims to establish new constraints to models of formation and evolution of galaxy groups , specially of compact groups , which are a key part in the evolution of larger structures , such as clusters .
In this paper we present three additional groups ( HCG 15 , 35 and 51 ) using deep wide field B and R band images observed with the LAICA camera at the 3.5m telescope at the Calar Alto observatory ( CAHA ) .
This instrument provides us with very stable flatfielding , a mandatory condition for reliably measuring intragroup diffuse light .
The images were analyzed with the OV_WAV package , a wavelet technique that allows us to uncover the intragroup component in an unprecedented way .
We have detected that 19 , 15 and 26 % of the total light of HCG 15 , 35 and 51 , respectively , is in the diffuse component , with colours that are compatible with old stellar populations and with mean surface brightness that can be as low as 28.4 ~ { } { B~ { } mag~ { } arcsec ^ { -2 } } .
Dynamical masses , crossing times and mass to light ratios were recalculated using the new group parameters .
Also tidal features were analyzed using the wavelet technique .
