Why Tom Gehrels, Ingrid van Houten-Groeneveld, Cornelis Johannes van Houten are they forget ? If one see an asteroid discovered by the Palomar-Leiden Trojan Survey (numero P-L) one see that it is always discovered by the this 3 persons.
He y have he another discoverer in this survey?
And why you speak not of the method ? in the note over, for example, the asteroid 1744 Harriet (6557 P-L), the JPL Small-Body Database Browser said : "These planets have all been discovered as a result of the Palomar survey of faint minor planets and subsequently identified with planets observed at other oppositions. In Sept. and Oct. 1960, T. Gehrels exposed 130 plates with the 122 cm Schmidt camera at Palomar. In the following years C. J. van Houten and I. van Houten-Groeneveld measured these plates astrometrically and photometrically at Leiden. P. Herget, Cincinnati, computed the orbits of the planets found on the NORC computer, Dahlgren, Virginia, USA."
