TESTB2/CCD in_frm [out_id] [row_ran] [col_ran]
	Compute row and column average of a (averaged) bias frame
\us\pu
Purpose:    
	Compute row and column average of a (averaged) bias frame
\up\sy
Syntax:     
	TESTB2/CCD in_frm [out_id] [row_ran] [col_ran]
\ys\pa
        in_frm =  input frame; 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 
        row_ran = Range of rows in the master bias frames to be averaged.
                  Default is all rows.
\ap\pa
        col_ran = Range of columns in the master bias frames to be averaged.
                  Default is all columns.
\ap\no
Note:
        This command is the second of a series of tests on BIAS frames: B1
        to B5. See the command TESTBA/CCD.
\\
        From the combined bias frame rows and columns are averaged and plotted.

        to the CCD Chapter in Volume B of the ESO-MIDAS Users' Guide.

Output:
        The command will stored the outputs in a number of ascii and 
        postscript files (preceding by the identification string out_id):\\
           `out_id'_avcol.bdf:  MIDAS image containing the column average;\\
           `out_id'_avrow.bdf:  MIDAS image containing the row average;\\
           `out_id'_aver.ps:    postscript file with the plots of the column
                                and row average;

Examples:
\ex
        TESTB2/CCD BIAS BS median ? 350,500
        Run the test  on the frame BIAS. Do averaging over all rows
        and over the column range from 350 to 500.
