eclipse


 ECLIPSE -- like 'COMDAT' computes data equivalent to a particular image,
            but also accounts for eclipses and therefore requires you to
            specify parameters that allow it to convert from velocity to
            position (it assumes a "keplerian" flow).

 Parameters:

   IMAGE     -- The image file to load
   TEMPLATE  -- TRUE if template data file is to be used otherwise the user
                must define pixels sizes etc.
   If TEMPLATE

     DATA      -- Data file containing example format data

   Else

     NPIX      -- Number of pixels/spectrum        
     NSPEC     -- Number of spectra
     VDATA     -- Velocity km/s/pixel
     WCEN      -- Central wavelength (Angstroms)
     WIDTH     -- Phase width of exposures

   OUTPUT    -- Calculated data file name
   KW        -- White dwarf's semi-amplitude
   KR        -- Red star's semi-amplitude
   IANGLE    -- Inclination angle
   OVER      -- Over sampling factor. This makes the program
                over-sample the velocity grid to produce
                smoother time dependence. You should be very careful
                with this parameter as the computation time scales as
                OVER**2.
   RMAX      -- maximum distance in terms of RL1 to attempt computation
                of eclipse. Any emission that translates to a place
                beyond this radius is assumed not eclipsed. You could
                allow this to extend beyond 1, but I don't know how
                it will cope with points that end up inside the mass
                donor.

   If NADD

     CONT      -- Effective continuum for noise computation
     NOISE     -- Signal-to-noise in effective continuum
     SEED      -- Seed integer to start noise generator if NADD

This command belongs to the class: extra
