The routine SXT_TEEM should be used to compute temperatures from SXT
filter data. This routine will compute the filter ratio and then determine the
temperature and emission measure and uncertainties. Some example calling sequences are:
IDL> sxt_teem, index1, data1, index2, data2, Te
IDL> sxt_teem, index1, data1, index2, data2, Te, EM, dTe, dEM,subs=subs
IDL> sxt_teem, index1, data1, index2, data2, Te, EM, dTe, dEM,$
IDL> sat1=sat1,sat2=sat2,unc1=unc1,unc2=unc2
IDL> sxt_teem, index1, data1, index2, data2, Te, EM, dTe, dEM,$
IDL> sat1=sat1,sat2=sat2,unc1=unc1,unc2=unc2,/average
Note that Te (K) and EM (cm
) are returned as log10 values as are their
uncertainties. Some ratios may have invalid temperatures and these are flagged
with Te=0. 
and 
do not need to be exposure normalized if
and 
are SXT index structures (since the and parameters can
optionally be scalar values which are the X-ray filter numbers).
The results may be displayed using different techniques. One way is to use a user
contributed routine:
IDL> tv_teem,Te,dTe,level=.3
where level= specifies the maximum value of dTe which is displayed. This
is a convenient way to suppress the display of pixels that have low statistical
significance.
