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.

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
