     92Now you can check if the reading rawdata is working::

     95  showing test of iterator of RawData class
     96  in order to test the SlowData classe please use: ./pyfact.py fits-file-name

     108This should work at ISDC only, but if it does not work, please ask somebody for help.

     1106. Tiny examples
     111===============
     112
     113one may interactively play with the two most important classes *RawData* and
     114*SlowData* from module pyfact...
     115
     116*datafilepath* and *calibfilepath* should be adjusted in case you are not working
     117on the ISDC cluster.
     118
     119explore class RawData::
     120
     121  from pyfact import RawData
     122  # or from pyfact import *
     123 
     124  datafilepath = '/fact/raw/2012/03/04/20120304_018.fits.gz'
     125  calibfilepath = '/fact/raw/2012/03/04/20120304_012.drs.fits.gz'
     126  run = RawData(datafilepath, calibfilepath)
     127  event = run.next()
     128 
     129  type(event)
     130 
     131  print 70*'*'
     132  for key in event:
     133    print 'key  :', key
     134    print 'value:', event[key]
     135    print 70*'*'
     136
     137for historical reasons, an event contains *data* and *acal_data*, where *acal_data*
     138would be the DRS amplitude calibrated data, and *data* would be uncalibrated.
     139But since the calibration was moved into a C++ class, for better performance,
     140these keys now contains the same data.
     141
     142loop over RawData::
     143
     144  from pyfact import RawData
     145  # or from pyfact import *
     146 
     147  datafilepath = '/fact/raw/2012/03/04/20120304_018.fits.gz'
     148  calibfilepath = '/fact/raw/2012/03/04/20120304_012.drs.fits.gz'
     149  run = RawData(datafilepath, calibfilepath)
     150
     151  for event in run:
     152    print 'event_id:', event['event_id']
     153    # the data can be found in event['data']
     154
     155have a look at some SlowData::
     156
     157  :~$ cd /fact/aux/2012/05/30
     158  :/fact/aux/2012/05/30$ python
     159 
     160  from pyfact import SlowData
     161  file = SlowData('20120530.FTM_CONTROL_TRIGGER_RATES.fits')
     162  file.show()
     163 
     164
     165have a look at the *columns*, that are available::
     166
     167  'columns': {'BoardRate': (40L, 4L, 'E', 'Hz'),
     168             'ElapsedTime': (1L, 4L, 'E', 'sec'),
     169             'FTMtimeStamp': (1L, 8L, 'K', 'us'),
     170             'OnTime': (1L, 4L, 'E', 'sec'),
     171             'OnTimeCounter': (1L, 8L, 'K', 'us'),
     172             'PatchRate': (160L, 4L, 'E', 'Hz'),
     173             'QoS': (1L, 4L, 'J', ''),
     174             'Time': (1L, 8L, 'D', 'MJD'),
     175             'TriggerCounter': (1L, 4L, 'J', 'int'),
     176             'TriggerRate': (1L, 4L, 'E', 'Hz')},
     177
     178choose the *columns* you would like to retrieve from the file::
     179
     180  file.register('TriggerRate')
     181  file.register('Time')
     182  # or in case you are unsure
     183  file.register('all')
     184
     185check, what happened. file has got some new members::
     186
     187  file.show()
     188
     189but they are all zero. Now one should call *next()* in order to get
     190the file contents row by row::
     191
     192  file.next()
     193  file.show()
     194
     195or loop over the file::
     196
     197  counter = 0
     198  for row in file::
     199    if counter > 10:
     200      break
     201   
     202    print row.Time, row. OnTime
     203    counter += 1
     204
     2057. Old way of creating the so files
