              EXPERIMENTAL\ Language Summary

    These  commands  are  experimental and their name, calling sequence, and
    behavior are subject to changes without advise.

    FILTER           Apply a filter on the R spectrum
    RMS              Compute the RMS of the index
    SUBTRACT         Compute T-R
    UNBLANK          Remove blanks in a Class TABLE
    VARIABLE         Create sic variables mapping the observation(s)
    WAVELET          Decompose the R spectrum into wavelets
1 FILTER
        EXPERIMENTAL\FILTER [/STORE]

    Compute the Mean Absolute Deviation of the R spectrum, and store the re-
    sult in R%HEAD%BAS%SIGFI if the option /STORE is present.
1 RMS
        EXPERIMENTAL\RMS  [/RESAMPLE  [NX  Xref  Xval  Xinc Unit]] [/NOCHECK
    [SOURCE|POSITION|LINE|SPECTROSCOPY|CALIBRATION]]

    Produce the RMS spectrum of the index.
1 SUBTRACT
        EXPERIMENTAL\SUBTRACT

    Compute the difference T-R. Consistency of the input spectroscopic  axes
    is checked. Output header is NOT IMPLEMENTED: T header is reused.
1 UNBLANK
        EXPERIMENTAL\UNBLANK [/MODE REJECT|NOISE|INTERPOLATE]

1 VARIABLE
        EXPERIMENTAL\VARIABLE Section1 [Section2 ...] [/MODE READ|WRITE|OFF]
    [/INDEX]

    VARIABLE /INDEX will read (from file) and save (in memory) in Sic arrays
    the  named  sections of all entries in the current index. The Sic arrays
    will be available in the structure IDX%HEAD%, under each named  section.
    Any  further  call to FIND and DROP (i.e. commands which modify the cur-
    rent index) will destroy the Sic arrays. For  efficiency  purpose,  they
    are not recreated implicitly, the command VARIABLE /INDEX must be called
    again instead.

    VARIABLE USER /INDEX will load the user section for all entries, if  the
    associated  hooks  to  the command are declared in Class. The Sic arrays
    will be available in the structure IDX%USER%<owner>%<title>%

    The option /MODE indicates to  create  read-only  (READ)  or  read-write
    (WRITE)  variables.  The  keyword  OFF  will delete the variables of the
    named sections and free their associated memory. WRITE is not allowed on
    /INDEX arrays.
1 WAVELET
        EXPERIMENTAL\WAVELET [/BASE [N]]

    Compute  the wavelets of the R spectrum, and store all the orders in the
    Sic array named WAVELET. If the option /BASE N is present, the N-th  or-
    der is subtracted from the R spectrum (default N is 5).
