## USAGE:

    beta_const_CT_t_exact = gsw_beta_const_CT_t_exact(SA,t,p)

## DESCRIPTION:

    Calculates the saline (i. e. haline) contraction coefficient of seawater
    at constant Conservative Temperature.

    Click for a more detailed description of the saline
    contraction coefficient at constant Conservative
    Temperature.

## INPUT:

    SA  =   Absolute Salinity                                       [ g/kg ]
    t   =   in-situ temperature (ITS-90)                           [ deg C ]
    p   =   sea pressure                                            [ dbar ]
            (ie. absolute pressure - 10.1325 dbar)

    SA & t need to have the same dimensions.
    p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & t are MxN.

## OUTPUT:

    beta_const_CT_t_exact  =  saline contraction coefficient                [ kg/g ]
                      at constant Conservative Temperature

## EXAMPLE:

    SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
    t =  [28.7856; 28.4329; 22.8103; 10.2600;  6.8863;  4.4036;]
    p =  [     10;      50;     125;     250;     600;    1000;]

    beta_const_CT_t_exact = gsw_beta_const_CT_t_exact(SA,t,p)

    beta_const_CT_t_exact =
