 No XMM data set given
 The specified table has already been processed with barycen
 The JPL ephemeris file was not found
 There is no position data available for a particular time — set time to NaN
 An EXPOSU table was selected as input table, in this case, any other EXPOSU table will be corrected.
corrective action: If you want to correct all the EXPOSU tables, introduce as input the EVENTS table.
 A keyword, representing the start or end date of the observation is missing from the input table
corrective action: The absolute time values may be wrong if this key word isn't set correctly. If this is important to you then add the keyword to the file header
 The date of the start or end of the observation, taken from the file header keywords, could not be understood
corrective action: Check that the DATE-OBS and DATE-END keywords are written correctly in the table header
