+The first step of using detselect to determine the appropriate detrend is to use the -search option, which returns a det_id for the requested detrend type for a specific date:
+{{{
+> detselect -search -det_type DARK -time 2012-05-15T02:02:02
+
+detExp MULTI
+
+detExp  METADATA  
+   det_id           S64       866            
+   iteration        S32       0              
+   filelevel        STR       chip            
+END
+}}}
+
+This example shows that for the given time (usually the dateobs value for the exposure of interest), the best DARK detrend is det_id 866.  Note that unless otherwise needed, det_type should not be a TEST type (DARKTEST, FLATTEST).  These are not generally used for science processing.
