+Optical processing (ELDA) failed but no Exit code is provided
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Q: The optical processing of one of my measurements failed (I get a status -127). However, when I check the Exit codes 
+to see the description of the problem, there is none. What does this mean?
+
+A: The reason for which ELDA failed it's not currently easy to find because 
+this module does not implement yet the setting of a specific error code for a 
+specific error. Based of past experience, when something like that happens is 
+due to a poor S/N ratio of the pre-processed signals. What you could try to do 
+to debug the problem is:
+
+* try to increase the S/N ratio of the pre-processed signals, for example by increasing 
+  the pre-processing vertical resolution or/and the pre-processing integration time.
+
+* look at the pre-processed signals produced for this measurement and see if 
+  there is something wrong in them.
