It is possible to display a light curve of the SXT image intensities using the routine LCUR_IMAGE. This routine is available from within STEPPER so the user can select the option by entering ``l''.
Some examples for calling LCUR_IMAGE directly are:
IDL> lcur_image, index, data
IDL> lcur_image, index, data, lcur
IDL> lcur_image, index, data, lcur, uncert, satpix
IDL> lcur_image, index, data, xsiz=512
IDL> lcur_image, index, data, xsiz=512, /poly
IDL> lcur_image, index, data, xsiz=512, /nonorm, subscript=subscript
index and data are input, and lcur is the output - an
array with the image intensities. uncert and satpix are optional
inputs which are the uncertainty and saturated pixel map which is returned
from SXT_PREP. If these two variables are passed, the routine will mark
points which are saturated or have high uncertainty.
The xsiz option will blow up the image to be 512 pixel wide (an 512
pixels tall if it is square) so that the selection of a region is simple.
-------- LCUR_IMAGE Options --------
Enter "p" to mark and plot light curves (loops until exited)
"m" to overplot all of the selected light curves
"r" to display the regions selected ("R" to make a hardcopy)
"s" to change the method to mark regions to plot. Currently: RECT
"d" to call "stepper" to refresh/display a new image
"z" to reset (zero out) all of the regions saved so far
"o" to enable/disable over plotting of new curves. Currently: DISABLED
"6" to enable/disable making 6 window plots. Currently: DISABLED
"h" to produce a hard copy of the most recent light curve
"H" to produce a hard copy of all selected light curves
"q" to exit LCUR_IMAGE ("x" will work too)
Enter your option (no return required). It is case sensitive.
The user can select several different areas on the image and overplot the light curves for each region. The light curves and regions are labeled so that they can be differentiated. Hardcopy options exist, along with several other capabilities. See the documentation header for the program and the Reference Guide for more details.
