\subsubsection{Input}  \begin{itemize}  \item \verb{\$arcname.fits} \verb|$arcname.fits|  -- Arclamp image where a \$arcname is something like Hg, Cd, Zn, Xe, etc... \item \verb{cat_Hg.fits.txt} \verb|cat_Hg.fits.txt|  -- Is the result of SexTractor on finding the locations of the Mercury lines. \item \verb{dome.fits_segments.npy} \verb|dome.fits_segments.npy|  -- Trace locations from trace finding module. \end{itemize}  \subsubsection{Output}  dome.fits\_segments.npy \verb|dome.fits_segments.npy|  contains a list (length the number of segments) of dictionaries. Each dictionary contains information about the location of each segment. \begin{itemize}  \item ok \verb|ok|  (boolean) -- The segment has more than 50 illuminated pixels \item mean\_ys \verb|mean_ys|  ([float]) -- The mean Y location of each pixel in the trace. It's length is usually between 200 to 270 pixels long. \item xs \verb|xs|  ([float]) -- The X location of each pixel. It's length is the same as means. The ridgeline of the trace is constructed from the points in (xs, means). \item trace\_sigma \verb|trace_sigma|  (float) -- The 1 $\sigma$ width of the trace. An in focus image should have a FWHM of about 2.5 pixels and thus sigma should be about 1.06. \item coeffs_y \verb|coeffs_y|  ([float]) -- A list of polynomial coefficients of order len(poly)-1 that is the best fit line to (xs, means). The bulk of this step's work is to derive poly. \end{itemize}
