Table\[variables\] lists the variables detected or characterized in the course of this study. Our sample includes 22 variables detected for the first time, and we give the first period determinations for six further stars previously known to be variable. All these periods are listed in column 6 of Table\[variables\]. We do not include in Table\[variables\] any previously known variables that we were not able to monitor (because they fell on CCD defects or outside our field of view). As nomenclature for new variables, we use LWxx with the numbering going from east to west. Near infrared $J$ and $K$ magnitudes were extracted from the 2MASS database and they are listed in columns 4 and 5. The 2MASS coordinates are given in columns 2 and 3.
