SXT_TEEM enables you to derive a
temperature map (Te) from two filters taken of the same region. Some sample
calls 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
index1,data1 should contain data for a single SXT filter. index2,data2
should contain data for a single SXT filter which is different from that
contained in index1 and data1.
The input data should be decompressed and background subtracted. If index is a vector, then the data arrays should be 3-d arrays (cubes).
Normally, SXT_TEEM will get the proper exposure times from the index. However, if you have renormalized the data in a non-standard manner, then use the t1=t1 and t2=t2 keyword to over-ride the value in index. t1 = Integration time in msec. If Image1 is a cube, then t1 must be a vector and whose length = n_elements(Image1(0,0,*))
The keyword option sum = sum calls SXT_SUMXY to rebin the data. The input image must be a 2-d or 3-d array sum must be an integral fraction of the number of X and Y elements. If either of the two preceding conditions is not met, summing is not done.
If data1 is a cube, Te will be computed for each image by default. If subs=subs is present, subs should contain the indices of image pairs to analyze.
The keyword option thresh1=thresh1, thresh2=thresh2 sets the level above which data are considered for processing. The level is set on the background subtracted, rebinned data values. If sum=2, then you must increase the value of thresh1 by a factor of 4 to have the same effect.
