Aims. Our goal is to estimate empirically the cosmic variance that affects merger fraction studies based on close pairs for the first time. Methods. We compute the merger fraction from photometric redshift close pairs with 10 h-1 kpc ≤ rp ≤ 50 h-1 kpc and ?v ≤ 500 km s-1 and measure it in the 48 sub-fields of the ALHAMBRA survey. We study the...
