The DATACUBE peakmap script will generate a line-strength map. The interface to this script is very similar to that of the velmap script discussed earlier, and it also generates final output in a similar form, see the figure. Much like the velmap script the peakmap script allows you to manually refit any spectrum that you think may have been poorly fitted by the automatic process.
It should be noted that generating a passband image of a line region, and a line-strength map using the peakmap script, should yield similar results. If you are worried about how accurately the automatic fitting of gaussians is doing on a particularly noisy image, then generating a line-strength map and making this comparison is an easy way of deciding a level of trust in your velocity maps, as these are generated using the same fitting algorithms.
