\end{itemize}  \subsubsection{Output}  \verb|dome.fits_segments.npy| \verb|fine.npy|  contains a list (length the number of segments) of dictionaries. Each dictionary contains information about the location wavelength solution  of each segment. \begin{itemize}  \item \verb|ok| (boolean) \verb|Elements derived from Trace step|  -- The segment has more than 50 illuminated pixels This file contains trace locations described abvoe  \item \verb|mean_ys| ([float]) \verb|lambda_rss|  -- The mean Y location Root-sum of square residuals  ofeach pixel in  the trace. It's length is usually between 200 wavelength solution  to 270 pixels long. measured line locations.  \item \verb|xs| ([float]) \verb|$lambda|  -- The X pixel  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). given arclamp lines (used for debugging purposes).  \item \verb|trace_sigma| (float) \verb|lambda_coeff|  -- 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 \verb|coeffs_y| ([float]) -- A list of Chebyshev  polynomial coefficients (can be evaluated with \verb|chebval|)  oforder len(poly)-1 that is  the best fit line to (xs, means). wavelength solution.  The bulk index value starts at the 0 location  of this step's work is to derive poly. the bounding box.  \end{itemize}
