I use the caption package to have figure titles above and notes below the figure. I follow this suggestion to define a new command that calls the caption* command with appropriate settings. However, the space between the figure and the note (another caption) is too large. How can I make it smaller? The skip setting only changes the space after the note. I tried to specify abovecaptionskip directly but that is "undefined in families `caption'".
Here are the relevant code chunks that I use, and below a screenshot what is produced where I highlighted the space I want to decrease.
# preamble
\usepackage[bf, justification=centering]{caption}
\newcommand\fnote[1]{\captionsetup{font=small,justification=justified}\caption*{#1}}
figure
\begin{figure}[htb]
\caption{Comparison of the retirement effect estimate by gender}
\begin{center}
\includegraphics[width=\textwidth]{figure}
\end{center}
\fnote{{\it Notes:} The dots ...}
\end{figure}
