New, extended version of Table: Non-gravitational Oort spike comets (26 objects)

Reciprocals of semimajor axes are given in units of 10-6 AU-1

Nongravitational parameters A1, A2 and A3 are given in units 10-8 AU/day2

tau shift - time displacement of the maximum of the function g(r) relative to perihelion is given in days
