private 
Generate CALDB directory structure for one observation identifier

The structure is given by

    data/<tel>/<inst>/bcf/<obsid>

where <tel> is "cta" and <inst> is the instrument specified in the
CALDB constructor (the instrument may be used for different array
configurations).

Parameters

irf : dict
    IRF metadata dictionary

Returns

def cscripts.csroot2caldb.csroot2caldb._open (   self,

private 
Open existing or create new calibration

The actual version will put all calibrations in the same file, although
each part of the response function will have its own logical name. We
can thus easily modify the script to put each calibration information
in a separate file

Parameters

irf : dict
    IRF metadata dictionary
ds : dict
