The POINTING fits in Chef can now be combined across several scans.  This is
indicated by adding the second parameter, C, to the SCAN <scan#> command.
The recipe for doing a pointing fit is then expanded to:

    SCAN <scan 1>			Begins a new average with scan <scan 1>

    SUBSCAN
    STORE				Do these two for every subscan
    ...

    POINTFIT				Optional.  Display results so far

    SCAN <scan 2> C			Prepare to add data from <scan 2> to
    					that from <scan 1>
    SUBSCAN
    STORE				Do these two for every subscan
    ...

    POINTFIT				Optional.  Display results so far

    SCAN <scan 3> C			Prepare to add data from <scan 3> to
    					that from <scan 1> and <scan 2>
    SUBSCAN
    STORE				Do these two for every subscan
    ...

    POINTFIT				Do the final fit

The resulting plot will be labeled with the first scan number and also a 
comment noting how many scans and subscan's have been combined.

The Online Chef will do the equivalent if one adds the option, /APPEND, to
the POINTING command for <scan 2> and <scan 3>.

If one executes within Chef, @PROC:CHEFINIT DRUM, one will get several 
abbreviations defined to make manual pointing fits easier to do:

    PL		Equivalent to one SUBSCAN & STORE pair
    PL2		Equivalent to two SUBSCAN & STORE pairs
    PL4		Equivalent to four SUBSCAN & STORE pairs
    PF		Same as typing POINTFIT
    PLA		Same as as many SUBSCAN & STORE pairs as exist for this scan
    COMB_FIT    Combines the scans specified into a single pointing fit

The COMB_FIT command takes two parameters, the first and last scan number to do
(and all scans in between):

    COMB_FIT n1 n2

    If you want to use COMB_FIT to combine scans that are not contiguous,
you can fool it by typing:

    COMB_FIT n1 "n1 ..."
where  ... is the list of blank separated individual scan numbers (not 
including the first one, n1) and may even include one or more x to y by z
phrases (i.e. the SIC for-loop syntax).


The SUPPLY POINTING command in CHEF has been enhanced.  One can now control
whether the pointing fits get written to the OBS and System pointing files:

    SUPPLY POINTING SAVE	Turns the writing on

    SUPPLY POINTING NOSAVE	Turns the writing off (the offline default)

    SUPPLY POINTING ONLINE	Turns the writing on & mails fits to OBSERVE
    				(Only useful for Online Chef)

    SUPPLY POINTING STOP_ONLINE
    				Stops mailing fits to OBSERVE (offline default)
