LC_BSC plots light curves of selected spectral regions.
IDL> lc_bsc, bsc_index, bsc_data, t, y, chan=chan,/flux
This program first plots a spectrum at the peak of the flare. The user can
select a spectral region with the cursor. The light curve derived from the sum
of wavelength points within this region is returned in the array 
. The time (UT)
is returned in 
. If the BSC data are flux calibrated, then using the FLUX
keyword will return the light curve in units of photons cm
s
.
The optional keyword over will overplot successive light curves.
