TESTB5/CCD in_cat [out_id] [area] [size,fac]
	Do the statistics of the bias frame is a catalogue.
\us\pu
Purpose:    
	Do the statistics of the bias frame is a catalogue.
\up\sy
Syntax:     
	TESTB5/CCD in_cat [out_id] [area] [size,fac]
\ys\pa
        in_cat =  input (with the extension .cat) catalogue of frames to be 
                  combined; no default
\ap\pa 
        out_id =  output identifier for the output of the test prodedure. 
                  All output (i.e. frames, listings and plots) will start 
                  with this identifier. Default is BIAS.
\ap\pa 
        area =    area which the statistics is computed; Default is whole image
                  area.
\ap\pa
        size,fact = size of smoothing box used for median filtering and
                  decimation factor for frame size reduction. Default is 5,16.
                  The default size 5 for the filtering implies a filtering
                  over boxes of 11 by 11 pixels.
\ap\no
Note:
        This command is the fifth test of a series of tests bias frames: B1 to
        B5. See the command TESTBA/CCD.
\\
        For each input frame in the catalogue determine the mean BIAS and 
        standard deviation AFTER hot pixel correction, box averaging and 
        median filtering. Finally, the overall mean bias level and sigma are
        computed.
\\
        For more details about the various combining methods, please refer 
        to the CCD Chapter in Volume B of the ESO-MIDAS Users' Guide.
\on\op
Output:
        The statistical data wil be stored in the table `out_id'_mean.tbl.

Examples:
\ex
        TESTB5/CCD bs_cat.cat BS 
        Do the statistics on all frame in the catalogue bs_cat. Use the 
        defaults for filtering and rebinning.
