Photometric parameters of the comet Kohoutek 1973f
On the basis of the author's own photoelectric measurements and those ofother authors, the photometric parameters of the comet Kohoutek 1973fwere derived. The authors used their own graphical method to reduce theobservations; this enables one to transform the observations, obtainedat different focal diaphragms, to any diaphragm and, thus, also to anylinear diameter of the comet. The photometric parametersmzero and n were computed for 5 selected intervals and for alinear diameter of the inner coma of 40.000 km. The relation betweenthese parameters was determined. The parameter n varies little with thedistance of the comet from the sun, and the comet did not display suddenchanges of brightness in the interval of observation.
