Uneven vertical space in tablenotes when using `subdepth`

Question

When using subdepthfor nice looking equations, the tablenotes in threeparttable get messed up. Any idea how to get even vertical space between items in tablenotes? Have tried using \usepackage[low-sup]{subdepth} with no good result.

MWE:

\documentclass{article}
\usepackage{threeparttable}
\usepackage{subdepth}
\begin{document}
\begin{equation}
    A = \frac{\left(\phi+\epsilon_A^\prime\right)-\epsilon_A}{\left(1+\epsilon_A^\prime\right)-\epsilon_A}
\end{equation}
\begin{table}[htbp]
  \caption{}
    \label{tableA}
    \centering
    \begin{threeparttable}
    \begin{tabular}{ll}
\hline
Name    & Value \\
\hline
TestA\tnote{a} & 1000000000000000000000000 \\
TestB & 10 \\
TestC & 10 \\
TestD & 10 \\
\hline
  \end{tabular}
    \footnotesize   
    \begin{tablenotes}
        \item[a]{Salinity data from somewhere}
        \item[b]{Chemical product sheet}
        \item[c]{Standard density of water}
        \item[d]{Calculated value}
    \end{tablenotes}
    \end{threeparttable}
\end{table}
\begin{table}[htbp]
  \caption{}
    \label{tableB}
    \centering
    \begin{threeparttable}
    \begin{tabular}{ll}
\hline
Name    & Value \\
\hline
TestA\tnote{a} & 1000000000000000000000000 \\
TestB & 10 \\
TestC & 10 \\
TestD & 10 \\
\hline
  \end{tabular}
    \footnotesize   
    \begin{tablenotes}
        \item[a]{Salinity data from somewhere}
        \item[a]{Chemical product sheet}
        \item[a]{Standard density of water}
        \item[a]{Calculated value}
    \end{tablenotes}
    \end{threeparttable}
\end{table}
\end{document}

Yes @Bernard, it works for tablenotes, but then the subscript A is not aligned any longer in the equation :-( — TobiasDK, Jun 10 '16 at 16:10
The increased raising of the exponent causes the b line to be too high, so the \lineskip mechanism is used. This doesn't happen with the a exponent, because it lacks the ascender. — egreg, Jun 10 '16 at 16:22
@egreg, can I use some \phantom function to mimic the vertical size of the letter b in all items? — TobiasDK, Jun 10 '16 at 16:29
\vphantom{b}in all items will do the job. Not the most beautiful solution, but it works!?! — TobiasDK, Jun 10 '16 at 16:34
One other ugly feature is the bad horizontal alignment of the text after the items. The letter S is far more to the left than the letter C! — TobiasDK, Jun 10 '16 at 16:53

From the help of @egreg and @Bernard, I found a solution myself. Using either \vphantom{b} or \smash{a-b-c-d} will make the items align vertical. Notice I have added some horizontal space in the tablenotes to get the text proper aligned.

\documentclass{article}
\usepackage{threeparttable}
\usepackage{subdepth}
\begin{document}
\begin{equation}
    A = \frac{\left(\phi+\epsilon_A^\prime\right)-\epsilon_A}{\left(1+\epsilon_A^\prime\right)-\epsilon_A}
\end{equation}
\begin{table}[htbp]
  \caption{$\backslash$vphantom\{b\}}
    \label{tableA}
    \centering
    \begin{threeparttable}
    \begin{tabular}{ll}
\hline
Name    & Value \\
\hline
TestA\tnote{a} & 1000000000000000000000000 \\
TestB\tnote{b} & 10 \\
TestC\tnote{c} & 10 \\
TestD\tnote{d} & 10 \\
\hline
  \end{tabular}
    \footnotesize   
    \begin{tablenotes}
        \item[\vphantom{b}a]{\hspace{0.3pt}Salinity data from somewhere}
        \item[\vphantom{b}b]{\hspace{-.3pt}Chemical product sheet}
        \item[\vphantom{b}c]{\hspace{0.3pt}Standard density of water}
        \item[\vphantom{b}d]{\hspace{-.3pt}Calculated value}
    \end{tablenotes}
    \end{threeparttable}
\end{table}
\begin{table}[htbp]
  \caption{$\backslash$smash\{a-b-c-d\}}
    \label{tableB}
    \centering
    \begin{threeparttable}
    \begin{tabular}{ll}
\hline
Name    & Value \\
\hline
TestA\tnote{a} & 1000000000000000000000000 \\
TestB\tnote{b} & 10 \\
TestC\tnote{c} & 10 \\
TestD\tnote{d} & 10 \\
\hline
  \end{tabular}
    \footnotesize   
    \begin{tablenotes}
        \item[\smash{a}]{\hspace{0.3pt}Salinity data from somewhere}
        \item[\smash{b}]{\hspace{-.3pt}Chemical product sheet}
        \item[\smash{c}]{\hspace{0.3pt}Standard density of water}
        \item[\smash{d}]{\hspace{-.3pt}Calculated value}
    \end{tablenotes}
    \end{threeparttable}
\end{table}
\end{document}

the different horizontal alignment of text after the footnote labels is because the horizontal space allowed for the labels is only .5em (defined in \TPTnoteSettings), which is a hair too narrow for many letters. redefining the width of this space in the preamble (by patching the definition of \TPTnoteSettings) would be cleaner than adjusting individual lines of the notes. — barbara beeton, Jun 10 '16 at 18:04
@barbarabeeton, I tried using @Heiko Oberdiek solution: http://tex.stackexchange.com/a/181015/49888, with \labelsep instead of \itemsep, but it will not align the text, it only add space between label and text. Is there another function to use instead? Thanks. — TobiasDK, Jun 11 '16 at 07:19
