\begin{figure}[htb]

\includegraphics[scale=0.8]{Fig1}

\caption{Our attempts to reproduce the wideband data with a binary
orbit for WR 137. Both binary models adopted the values of
\citet{2005MNRAS.360..141L}; the missing angular parameter ($\Omega$ ,
longitude of the Ascending Node) was varied to find the best fit to
the Position Angle and separation derived from interferometric
measurements at a particular phase in two cases.  The resulting models
are shown for \citealt{2010RMxAC..38...54R}, yielding
$\Omega=112\degr$, and the value that best agrees with our data,
$\Omega=137\degr$.  Both agree with the separations predicted by
\citealt{2005MNRAS.360..141L} to within their published error bars.
The data point from PTI's NW baseline was taken in poor weather
conditions, so we do not consider it to be very reliable.}

Lo siento si es demasiada información, esta es mi primera publicación y quiero ser exhaustiva.

Respuesta1

Como su problema aparece solo en la segunda ejecución, es algo que se rompió cuando se escribió en el archivo "lof" (lista de figuras) en la primera ejecución. Esto normalmente se debe a un comando frágil en un título y a ver las advertencias.

LaTeX Warning: Citation `[' on page vi undefined on input line 5.

Antes del error, lo más probable es que los comandos de cita en el título sean los culpables. Entonces, sin verificar más, supongo que agregar \protectdelante \citety/o \citealtresolverá este problema.
