_______________________________________________________________________________ FS FLATSPEC is a module which flattens the continuum of a spectrum by fitting polynomials to continuum segments between mean X, Y points in spectral rows, and then dividing the original spectrum by the interpolated values. The bands whose averages are used to form the polynomials can be input manually or with a graphics device. _______________________________________________________________________________ Enter an option: 9-SEP-2004 13:40:13.97 OPTION=FS FLATSPEC, Version 5 Open the file to have spectra flattened Enter the filename: (<CR> for default) FILE_IN=DDTEST There are 2 maps in the file Reading from the file 2 rows of 500 pixels in R4 format Open the output file Enter the filename: (<CR> for default) FILE_OUT=DDTEST2 Writing to an existing file There is one map in the file 1 rows of 500 pixels in R4 format Enter the input map numbers: (default = all) MAPS_IN=2 Enter the output map number: (default = 1 after last map) MAPS_OUT=1 Enter the input row numbers: (default = all) ROWS=2 Enter the output row numbers: (default = all) ROWS=1 Enter the method to use for estimating the continuum values: PF = Polynomial fit PI = Polynomial interpolation (default) METHOD= PI Enter the degree of the polynomial for continuum interpolation: (default = 3) DEGREE_INTERPOLATION= 3 ....If a polynomial fit had been selected, the user would have been prompted for the degree of the polynomial with a default of 6. Enter the value to set the continuum to: (default = average of input rows between lowest and highest columns) VALUE= 0.000000E+00 ....The default was taken Enter the input method: G = Graphics Device (default) M = Manual Input INPUT_METHOD= G After the plot is drawn, press C to turn on the cursor. Then position the cursor at the left end of the first band (low wavelength end) of continuum wavelengths to be fit and press the <CR>. Then position the cursor at the right end of the first band and press the <CR>. Repeat these steps for each additional continuum band to be used in the fit. Mistakes can be voided by pressing the - key. Press Q to turn off the cursor and <CR> to proceed. Press the <CR> when through reading these instructions THROUGH= T Enter the plot devices: S = SAOimage -S = SAOimage, no erasure of screen G = Graphics terminal (VT100/Retrographics and Visual 550) G4 = Graphics terminal emulator (Versaterm-Pro) X = Xterm (default) XG = Xgterm F = File DEVICES= X Coordinates requested X= 5041.129 Y= 993.6365 X= 5056.525 Y= 996.5692 X= 5085.851 Y= 998.0355 X= 5102.712 Y= 996.5692 X= 5134.238 Y= 993.6365 X= 5157.698 Y= 992.1702 X= 5187.023 Y= 993.6365 X= 5212.684 Y= 993.6365 X= 5360.777 Y= 990.7040 X= 5383.504 Y= 987.7714 X= 5405.499 Y= 987.7714 X= 5426.760 Y= 987.7714 X= 5459.018 Y= 981.9064 X= 5473.681 Y= 986.3051 X= 5500.073 Y= 981.9064 X= 5510.337 Y= 981.9064 Coordinates request canceled 8 bands were chosen to be fit between the limits of 5041.50 and 5510.50 .
