2.3.5 Displaying the BSC Data

 

The light curve and spectra selected from the light curve (from the BSC file or structure) may be plotted with PLOT_BSC. This program may be used interactively if desired, and can also be used to overplot fitted spectra (if FIT_BSC has been called with the data). If there are multiple spectra, PLOT_BSC will provide a widget interface to select the spectrum to plot. An example is shown in Figure 3 which plots data which has been fit using FIT_BSC.

A light curve of FIT_BSC results can be produced with the FIT_BSC_PLOT. An example plot is shown in figure 4.  
IDL> fit_bsc_plot, bsc_index
  Note that FIT_BSC_PLOT displays the non-thermal broadening, or turbulent velocity as a function of time. The routine BCS_BROAD is used to make the conversion between line broadening and velocity. FIT_BSC will optionally fit a second component with an upflow velocity as one of the degrees of freedom.     A light curve of selected wavelength regions of a set of spectra can be produced with LC_BSC.
IDL> lc_bsc,bsc_index,chan=n
  A psuedo-map of stacked BSC spectra can be produced with MAP_BSC.
IDL> map_bsc,bsc_index,chan=n
