COMDAT -- computes data equivalent to a particular image. This can be subtracted from real data to give data residuals. Comdat is also useful for simulating data. comdat uses exactly the same image to data routine as optscl and memit and should therefore give the same chi**2 (for the same image and data). FIGARO variables: 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 CALC -- Calculated data file name NADD -- TRUE if noise is to added to data if NADD CONT -- Effective continuum for noise computation NOISE -- Signal-to-noise in effective continuum ISEED -- Seed integer to start noise generator if NADD
