The Puppis field was observed between 2011 and 2014 in the search for transitingextrasolar planets. To characterize the field, an automatic variable search was applied asdescribed by Fruth et al. (2012). With the automatic procedure 1829 new variables werediscovered and 26 previously known variables were confirmed (Dreyer et al. 2018). Beyond this work, the data was also analysed for potential transitevents by the Box-Fitting Least Square (BLS) method (Kovac et al. 2002, Fruth et al.2013). This yieldeda list of objects with tentative period, duration and depth, not included in the list ofDreyer et al (2018). The light curves of these potential candidates were visually inspectedand further modelled by TLCM, a transit light curve model to get thebasic parameters,developed by Csizmadia (2020). Thereby the period was confirmed or improved andthe type of binary was determined. Identification and variability data for the stars aresummarized in Tables 1–2; phase curves for each variable are presented in Figures 1–18.Photometry data files are also available online.
