Editing Culmination (section)

==Cases==
Three cases are dependent on the observer's [[latitude]] (''L'') and the [[declination]] (''δ'') of the [[celestial object]]:{{citation needed|date=November 2021}}
*The object is above the [[horizon]] even at its lower culmination; i.e. if {{math|<nowiki>|</nowiki> ''δ'' + ''L'' <nowiki>|</nowiki> > 90°}} (i.e. if in [[absolute value]] the declination is more than the colatitude, in the corresponding hemisphere)
*The object is below the horizon even at its upper culmination; i.e. if {{math|<nowiki>|</nowiki> ''δ'' − ''L'' <nowiki>|</nowiki> > 90°}} (i.e. if in absolute value the declination is more than the colatitude, in the opposite hemisphere)
*The upper culmination is above and the lower below the horizon, so the body is observed to rise and set daily; in the other cases (i.e. if in absolute value the declination is less than the [[colatitude]])

The third case applies for objects in a part of the full sky equal to the [[cosine]] of the latitude (at the equator it applies for all objects, because the sky turns around the horizontal north–south line; at the poles it applies for none, because the sky turns around the vertical line). The first and second case each apply for half of the remaining sky.{{citation needed|date=November 2021}}
