The individualized approach to 1/a-determination and the new distribution of original and future orbits nongravitational acceleration in the motion is detected for 50 per cent of investigated comets, in a few cases for the first time. Different sets of nongravitational parameters are determined from pre- and post-perihelion data for some of them. The influence of the positional data structure on the possibility of the detection of nongravitational effects and the overall precision of orbit determination is widely discussed. Eu sunt de parere ca ia un pic de timp pentru a analiza si digera datele. Si ca o reactie anti-alarmista din partea NASA/ESA la toate aberatille din lume ar da mai multa apa la moara alarmistilor.
