Contents: Description, Arguments, Usage, Examples, Sub-Functions, Related Functions, Source Supported Under Version: > 1.06 Current .dvrc Version: 1.24 Description Convert (resample/rescale) spectra from one IR instrument to another. See i2i_tutorial() or Instrument_to_Instrument_Resampling_with_i2i for some example usage. Arguments and Return Values Arguments: a spectrum, the to/from spectral ranges (either a pre-defined instrument or custom scale) Return Value: the resampled spectrum Usage Syntax: i2i(spec, from=STRING/VAL, to=STRING/VAL [, wave=BOOL][, cm=BOOL][, full=BOOL][, filters=BOOL][, descend=BOOL]) spec - a spectrum the size of from OR spec - can also be a structure with .data, .label, and .xaxis from - may be either a predefined instrument or a custom xaxis scale to - may be either a predefined instrument or custom xaxis scale Allowed 'from' instruments are lab1, lab2, tes, tes5, mtes and the data's xaxis Allowed 'to' instrument are lab1, lab2, tes, tes5, mtes, themis, aster, tims, master Both 'from' and 'to' can be arrays of xaxis values. Size of 'from' must equal size of spec Use 'to'=xaxis or 'from'=xaxis' to create or use customized output or input spectra. Default instrument input (from) spectra must be in ascending, cm-1 form Exception is converting broadband instrument from ascending wavelength to ascending cm This mode also returns the xaxis to avoid any confusion Ex: a = i2i(spect, from='themis', to='themis') returns 'a' in ascending cm form Default 'to' spectra are in ascending (low to high) cm for spectrometers or ascending wavelength for broadband instruments Options: wave=1 - returns spectra in ascending wavelength form cm=1 - returns spectra in ascending wavenumber (cm) form descend=1 - returns spectrum in descending wavelength or wavenumber order full=1 - returns both spectrum and xaxis filters=1 - returns spectrum, xaxis, and filter functions Note: Non-standard cm or wave modes return both spectra and xaxis Example Usage: speca = i2i(spec, from='lab1', to='themis') speca = i2i(spec, from='lab1', to='aster', wave=1) speca = i2i(spec, from='lab1', to='lab1', wave=1) speca = i2i(spec, from='tes', to='aster', cm=1) speca = i2i(spec, from='lab1', to= my_out_axis) speca = i2i(spec, from=my_in_axis, to= my_out_axis) speca = i2i(spec, from='tes', to= my_out_axis) Examples dv> spec=bbr(250,make_band(tes1)) 1x1x143 array of double, bsq format [1,144 bytes] dv> out=i2i(spec,from='tes',to='themis') doing broadband ................................1x1x10 array of float, bsq format [40 bytes] 6.753726484e-05 6.753726484e-05 5.671190956e-05 5.194100595e-05 4.685497697e-05 4.215575609e-05 3.838338307e-05 3.538411329e-05 3.262764949e-05 2.644573578e-05
