The output from rgsimplot is provided in Figure 6.3.
2) To plot a light curve from all events:
• evselect table=PiiiiiijjkkaablllEVENLInmmm.FIT:EVENTS withrateset=yes
rateset=PiiiiiijjkkaablllRATES
nmmm.FIT makeratecolumn=yes maketimecolumn=yes
timebinsize=100
> table – input event list.
> withrateset – create a light curve.
> rateset – name of output light curve.
> maketimecolumn – include an absolute time column.
> makeratecolumn – create a rate column.
> timebinsize – bin size (in seconds).
• dsplot table=PiiiiiijjkkaablllRATES
nmmm.FIT x=TIME y=RATE
The resulting curve is provided in Figure 6.4. Note that unlike Figure 6.2 these events have been extracted
across the whole detector and that our Good Time constraint has been adhered to.
3) To plot a spectrum with an approximate wavelength scale, use the mlambda table column rather than a
response matrix. One important caveat here is that all orders are superimposed on this table:
