Minimum component fitting procedure
-----------------------------------
Figure 10.12

The intermediate steps of the minimum component filter procedure applied to the
spectrum of a white dwarf from the SDSS data set (mjd= 52199, plate=659,
fiber=381). The top panel shows the input spectrum; the masked sections of the
input spectrum are shown by thin lines (i.e., step 1 of the process in Section
10.2.5). The bottom panel shows the PSD of the masked spectrum, after the
linear fit has been subtracted (gray line). A simple low-pass filter (dashed
line) is applied, and the resulting filtered spectrum (dark line) is used to
construct the result shown in figure 10.13.

Minimum component filtering is explained in Wall & Jenkins, as well as
Wall 1997, A&A 122:371.  The minimum component algorithm is implemented
in astroML.filters.min_component_filter
