Confirmed exoplanets in the NEA database with radii up to 2.5 R_Jup (open grey circles) and the seven exoplanet candidates identified in this work (black circles). The top panel shows the orbital radii calculated using the orbital period and stellar mass in Table A.5, i.e. Column “Orb. Rad.(1)” in Table A.6, and the bottom panel shows those calculated using the planet orbit-star radius ratio and the stellar radius in A.5, i.e. Column “Orb. Rad. (2)” in Table A.6. The error bars reflect the low and high values shown in the table.
