• TITLE: A Correction to v/d in Order to Calculate Hubbell-Lemaitre Constant H0

  AUTHORS: Luc R. M. Morin

  KEYWORDS: Hubbell-Lemaitre Constant, Hubbell Tension

  ABSTRACT: A distinction is made between: - velocity v e and distance d e at instant t e of photon emission; - velocity v r and distance d r at instant t r of photon reception. Mathematical integration of Hubbell law from instant t e to instant t r gives: d r / d e = e H 0 ( t r − t e ) . Depending on which couple ( v e , d e ) , ( v e , d r ) , ( v r , d e ) , ( v r , d r ) is considered, calculated ratios v/d would have to be corrected differently in order to calculate H 0 . If a survey calculates velocity ( v r ) at the instant of reception and distance ( d e ) at instant of emission, then in order to calculate H 0 , a correction inferior to 1 should be applied to ratio ( v r / d e ) . This would reduce Hubbell tension.
