1. 3 Color Scheme Range This section allows the user to change and control the color scheme used to determine the colors used in the honeycomb images for the Detectors Display see Figure 1 7 Two color schemes are available which both go from white high values to black low values Grey Scale and Heat The values for the color scheme are set to the average of the detector data within a user specified data range The range slider and the indices and values displayed next to it specify the abscissa range in the interferograms or spectra which is used to compute the average signal value and subsequently set the colors Note that only the abscissa indices not the values can be entered by the user Color scheme Range Color Scheme Grey Scale O Heat Figure 1 7 Control Panel Color Scheme 1 2 3 Preferences Panel This panel see Figure 1 8 allows the user to SpecExplorer e Select which detectors are to be displayed in the Bolometer Detector Array Display and the Thumb nails e Select the initial scale of the plots e Customize the title subtitle and legend entries for the main plot area e Select whether spectral phase is given in units of radians or degrees Note that the spectral phase o S is defined as tan 0 S Imaginary S Real S Select the quantity used in the plot when complex data are presented to either Real or Imaginary or Phase or Absolute This selection is only available if the prod2. by performing the steps in Section 1 3 select the range to be plotted on the thumbnail images e g from 25 cm to 40 cm 4 Inthe Preferences Panel check whether to get thumbnail images from all only the nominal or only the unvignetted detectors e g Unvignetted only 5 From the Thumbnails drop down menu on the Control Panel select to get thumbnail images from SLW SSW or the co aligned detectors on SLW and SSW see Figure 1 12 below SSwD2 hi dhii Bibi Bhihd biii Babii 0 014 0 012 ZAN 0 010 3 S o Ho ons SSWE2 me 0 004 morr mJ 0 014 E q re 0 0126 3 S q 0 000 awt ps J PER ENE VARE MENE eevee irene Gree d g he A 24 6 2 WH 32 34 36 MW 40 42 GA P 0 008 7J Wavenumber cm EZG E 4 4 SSWF2 J SSWD3 F T T T T T PEN T T T on E 4 T T T T T T T T T j aoit he q o oo E 4 0 014 E A 0 012 a eee ane J ooz F Fa hs e a o oo E f 4 oe eee eee eee eee eee ee ee ooo E j A 2 3 32 34 36 38 W 42 d 25 2 30 32 34 36 38 44W 42 F 0 008 E 4 Wavenumber em pb o08 E Wavennmber cm 4 Bo 00s F 4 Bo E 4 a 4 ma E SSWC3 ME q mororo one gor er aot J 0 002 E 3 E 3 0 002 E rA D J C 4 E ena aa J 0 000 E 4 F S 6 000 E 0 012 Fi J E L L it i i i 1 lg zl haa fe ji i 1 1 1 1 L ji 0 010 F ss 1 i i 1 i 1 1 i i 4 6 B WM 32 BM 36 38 4 42 E A 26 28 3
