    40 === Taking Exposure
    41 There are many ways to take an exposure, the simplest uses Python to issue the expose command.

    47   $ syscmd -v -l 'expose( seconds=20, observation=1234, exposure=1, x_binning=1, y_binning=1, type="sci" )'
    48   # VIRUS:
    49   $ syscmd -v -V 'expose( seconds=20, observation=1234, exposure=1, x_binning=1, y_binning=1, type="sci" )'
    50   }}}

    56 #!div style="font-size: 80%"
    57   {{{#!bash
    58   $ $HET_SRC_ROOT/camra/testing/lrs2.py  'expose( seconds=20, observation=1234, exposure=1, x_binning=1, y_binning=1, type="sci" )'
    59   $ $HET_SRC_ROOT/camra/testing/virus.py 'expose( seconds=20, observation=1234, exposure=1, x_binning=1, y_binning=1, type="sci" )'
    60   }}}
    61 }}}
    62 
    63 
    64 The exposure command will return once the readout has started.  The output FITS files will be available 40-50 seconds after that, depending on binning and disk I/O.  The return string of the expose command provides the output directory for that exposure.
    65 
    66 The exposure time is in the "seconds" parameter (minimum of 15).
    67 
    68 Observation and exposure determine the directories under which the data are grouped. An example output directory structure might be
    69 
    70 {{{
    71 /opt/data/20160309/lrs20000023/exp01/
    72                               /exp02/
    73 }}}
    74 
    75 So here two exposures are grouped under the observation number 23 taken on 20160309.
    76 
    77 The combination of observation/exposure must be unique for the UTC date. The agreed upon types are "sci", "cmp", "zro", "flt", "drk", "tst".
