Just to make sure I understand laser scan data. ranges is an array of scan distances. so:

ranges[0] shows scan distance at angle_min.

ranges[1] shows scan distance at angle_min+angle_increment.

ranges[2] shows scan distance at angle_min+(2*angle_increment) and so on? Is this correct

Your understanding seems correct.

@Martin Peris The values in the ranges array are the distances with reference to the sensor frame?

Sorry, I missed your comment. Yes, the values in ranges array are the distances with reference to the sensor frame (specified in the header of the message)
