// Objects of this class read txt file with survey (photogrammetry) data
-// and convert the data into AliAlignObjAngles of alignable PHOS volumes.
+// and convert the data into AliAlignObjParams of alignable PHOS volumes.
// It can be used as a base class, you need to override GetStripTransformation.
// AliPHOSSurvey inherits TObject only to use AliLog "functions".
