+ <h1 style="text-align: center;">1D fit Background Subtraction</h1>
+ <br>
+ <h2>Brief:</h2>
+ 1D fit Background Subtraction is a method of removing scattered
+ light from an image prior to subtraction. For each spatial column a
+ piecewsie function is fitted to the locations of "dead" fibres. A
+ median smoothing is then performed spectrally across all these
+ columns to define a smooth 2 dimensional model of scattered light
+ which is then subtracted from the image. The piecwise function is
+ instrument specific as follows:<br>
+ <br>
+ <h3>For AAOmega Instrument:</h3>
+ Model the scattered light a level plateau with Gaussian roll offs at
+ the edges.<br>
+ Divides the spatial pixel range into the three ranges:<br>
+ <ul>
+ <li> [x1,x2], A raising Gaussin</li>
+ <li> [x2,x3], A constant plateau</li>
+ <li> [x3,x4], A lowering Gaussian</li>
+ </ul>
+ Where x1 and x4 are the first and last points of the fitting data
+ and x2, x3 are located at 3*IGAP away from the first and last fibre
+ trace path (regardess of what status the are eg are they dead). <br>
+ The plateau is defined as the median of the Y_PTS. The Gaussians are
+ hard coded to have a sigma of 25 pixels and scaled so that
+ they pass through the points:<br>
+ <ul>
+ <li> (X_PT(1)
+ ,Y_PT(1) ) on the LHS and </li>
+ <li> (X_PT(Last),Y_PT(Last) ) on the RHS </li>
+ <li>and the plateau value at x=x2 and x=x3</li>
+ </ul>
+ <br>
+ <br>
+ <h3>For Other Instruments:</h3>
+ Model the scattered light a quadratic plateau with cubic roll offs
+ at the edges.<br>
+ Divides the spatial pixel range into the three ranges:<br>
+ <ul>
+ <li> [x1,x2], A raising cubic<br>
+ </li>
+ <li> [x2,x3], A quadratic/linear plateau</li>
+ <li> [x3,x4], A lowering cubic</li>
+ </ul>
+ Where x1 and x4 are .....<br>
+ <br>
+ The problem with the original code was the implementation of
+ iterative non-linear solvers which had a tendency to either fail to
+ converge to a solution or converge to a solution distant to the
+ correct least squares solution. As non-linear solvers are not
+ neccesary for this problem, this has been replaced with linear
+ solvers which will return the correct least squares solution.
+ However, there are cases where the correct least squares solution in
+ undesirable. In this situation we have added the constraint that the
+ cubic rolloffs should go to zero at X1 and X4<br>
