FUNCTION  fCosmoZfromDa

Returns a row with the first and second solution for the redshift given an angular diameter distance.

Parameters:
  • @AngularDiamDist float --/D Angular diameter distance --/U Mpc.
  • Returns a one row table (z1 float, z2 float)
  • z1 and z2 are the first and second solutions, where z1<=z2.
    select * from dbo.fCosmoZfromDa(380.467098233731)
    returns the row 0.0999999999999998 29.5344556200263
