Maximum and minimum within a certain time range

Continuing with the example above, find the maximum and minimum temperature in the last 3 hours of the data.

- xstart:=dm.quantity(xtimeinseconds[1],'s') # get the beginning time and 
					     # convert it into a quantity with
					     # units of seconds.
- xstart
[unit=s, value=13098.2014] 
- xstop:=dm.add(xstart,'3.h')		     # set the end time to the start
					     # time plus 3 hours.
- xstop
[unit=s, value=23898.2014]
- platetemp:=data.getcol("RC08_10_PLATE15K") # make an array of all the 15 K
					     # plate temperatures.
- mask:=xtimeinseconds<xstop[value]          # define a boolean mask that is
					     # true only within the time range.
- maxinfirst3:=max(platetemp[mask])          # get the max in this range
- mininfirst3:=min(platetemp[mask])          # get the min in this range
- print mininfirst3, maxinfirst3
