Issues with the cdfbuoyflx program and documentation on the computation of alpha and beta

[josuemtzmo]

Hello,
I just found another issue with the flags, not using the flag -teos10 in the cdfbuoyflx program does not change how the beta is computed. In other words, despite not having the flag, the default beta is computed with the beta_2d program (teos10) instead of the the beta_2d_80 program.

Additionally, I'm confused with how beta and alpha are computed. I've compared the values of beta and alpha from the CDFTools and python libraries sw and gsw. I've noticed that associated with the issue above, in the CDFtools both beta and alpha when using the using the beta_2d program is multiplied by a factor of 1026 (the reference density). I'm not sure if I'm missing something, but I found it extremely confusing and there is no documentation anywhere on this.

I haven't checked if this issue extends to other routines...
