Plot Light Curve When an image set is measured using the Aperture Photometry package, Mira can automatically generate a light curve showing the variation in magnitude versus time for selected target objects, standard stars, and check stars.
Values plotted are taken from data in the Apphot Pane. Column titles from the photometry table are used for the X Axis Variable, Y Axis Variable, and Y Axis Error Bar. In this example, a Julian Date offset was set in the Photometry Properties dialog, and that value is shown in the X Axis option. The light curve appears in a Mira
Plot Window and looks generally like those below. The
markers, colors, and trend lines for each group can be adjusted
using the ExamplesThe window below shows a single standard star plotted with error bars. This light curve was produced by measuring an image set using the settings shown in the dialog box above.
The two plots below show multiple targets,
standards, and a check star. In the upper plot, notice that,
because of the magnitude spread, the error bars do not appear even
though the option to plot error bars was checked. In the lower
plot, the
Notice that the top-most light curve for a target star has a marker that was changed to an open square after the plot was created, using the Plot Series Properties tool. The small vertical line inside the open square shows the magnitude error bars. The error bars for other points can be seen by enlarging the point. The plot below shows an enlarged view around the faintest standard star shown in the above plot.
PropertiesThe light curve is generated from Properties you enter into the Plot Light Curve Dialog. Objects to be plotted are specified using their Object number from the Apphot Pane To plot multiple objects, you can enter numbers separated by commas, like this: 1,2,5,12 or enter a sequence of numbers like this: 1-10. You can also mix the two formats, like this: 1,2,5,8-16,24. Plot Light Curve Properties
