Calculate multi algorithm ensemble average
Note, first you have to calculate the multi ensemble average with o->algorithm_average(/calc, /save, mask='com'). As the default resolution is a reduced resolution, you have to specify explecitely the scale=1, when you create the cws_stats object. If the average file is created, you can handle the average like a group by setting the group to 'AVG' and make plots like in the other examples (and of cause you can use the default reduced resolution again). By setting the group to 'NOBS' you can make plots of the number of algorithm observation.

Calculate multi algorithm ensemble standard deviation
Note, first you have to calculate (and save) the multi algorithm ensemble average like in the example before. Then you have to calculate the multi algorithm ensemble standard deviation. Like in the example before, you have to specify explecitely the scale=1, when you create the cws_stats object. If the standard deviation file is created, you can handle the absolute and relative standard deviations like a group by setting the group to 'STD_ABS' and 'STD_REL' respectively, and make plots like in the other examples (and of cause you can use the default reduced resolution again).
o=obj_new('cws_stats', scale=1)
