     32
     33for historical reasons, an event contains *data* and *acal_data*, where *acal_data*
     34would be the DRS amplitude calibrated data, and *data* would be uncalibrated.
     35But since the calibration was moved into a C++ class, for better performance,
     36these keys now contains the same data.

     52=========
     53
     54have a look at some SlowData::
     55
     56  :~$ cd /fact/aux/2012/05/30
     57  :/fact/aux/2012/05/30$ python
     58 
     59  from pyfact import SlowData
     60  file = SlowData('20120530.FTM_CONTROL_TRIGGER_RATES.fits')
     61  file.show()
     62 
     63
     64have a look at the *columns*, that are available::
     65
     66  'columns': {'BoardRate': (40L, 4L, 'E', 'Hz'),
     67             'ElapsedTime': (1L, 4L, 'E', 'sec'),
     68             'FTMtimeStamp': (1L, 8L, 'K', 'us'),
     69             'OnTime': (1L, 4L, 'E', 'sec'),
     70             'OnTimeCounter': (1L, 8L, 'K', 'us'),
     71             'PatchRate': (160L, 4L, 'E', 'Hz'),
     72             'QoS': (1L, 4L, 'J', ''),
     73             'Time': (1L, 8L, 'D', 'MJD'),
     74             'TriggerCounter': (1L, 4L, 'J', 'int'),
     75             'TriggerRate': (1L, 4L, 'E', 'Hz')},
     76
     77choose the *columns* you would like to retrieve from the file::
     78
     79  file.register('TriggerRate')
     80  file.register('Time')
     81  # or in case you are unsure
     82  file.register('all')
     83
     84check, what happened. file has got some new members::
     85
     86  file.show()
     87
     88but they are all zero. Now one should call *next()* in order to get
     89the file contents row by row::
     90
     91  file.next()
     92  file.show()
     93
     94or loop over the file::
     95
     96  for row in file:
     97    print row.Time, row. OnTime
     98
     99*row* is just be a copy of *file*, but inside the for loop, I think it is
     100convenient to access members of *row* rather than members of *file*.
     101I is just easier to understand for the reader, I think.
