The difference (in relation to the CCSD method) in the value (in a.u.) of the electron density determined at the ring critical point of the 2,2-dichloro-1-(1H-pyrrol-2-yl)ethan-1-one molecule. The different types of methods are represented by a colored background: LDA—pink, GGA—blue, M-GGA—orangeish, H-GGA—green, HM-GGA—violet, DH-GGA—beige, perturbational methods—gray.
