The procedure IUEMERGE may be used to join together two spectra with adjoining wavelength regions (e.g., SWP and LWP spectra, or adjacent orders in a high dispersion spectrum). The newsips keyword should be set if your spectra were processed with NEWSIPS so that IUEMERGE will realize that the quality flags (q1 and q2) are flags; otherwise they will be considered to be flags. The calling sequence is:
|W1,F1,q1||Wavelengths, fluxes, and optional quality flags for first input spectrum.|
|W2,F2,q2||Wavelengths, fluxes, and optional quality flags for second input spectrum.|
|KIND||The type of merging desired:
Splice vectors where the wavelength vectors equal (Å. In this case, the values of ``W1'' must be smaller than the values of ``W2''. Example:
will result in ``W3'', ``F3'', and ``E3'' being equal to ``W1'', ``F1'', and ``E1'' in the region <2000 Å but equal to ``W2'', ``F2'', and ``E2'' in the region >2000 Å.
'A' Average the fluxes in the region of overlap. Resample ``F2'' to the same wavelengths as ``W1'' and average ``F1'' and ``F2'' (weighted by ``Q1'' and ``Q2'', if they are present).
'M' Merge (concatenate) all values of ``W1'' and ``W2'', ``F1'' and ``F2'', and ``Q1'' and ``Q2'', keeping all data points.
|W3,F3,q3||Output (merged) wavelengths, fluxes, and optional quality flags.|
You must either include no quality flags whatsoever, or include q1, q2, and q3.
