Flow chart of the input and output files.
In most of the files below, "-###" is the frame (or observation) number of the object file exposure. For example, frame number 34 would be "-034" and the object spectrum file would be "Flux-034.fits".
| Type ( filename ) | Description |
|---|---|
| Object Spectrum (Flux-###.fits) | Contains spectrum of object in 2-D format (each row is an echelle order). (more info) |
| Error Spectrum (Err-###.fits) | Contains (one sigma) formal error spectrum for the object. (more info) |
| Sky Spectrum (Sky-###.fits) | Contains the nightsky or background spectrum. (more info) |
| Flat Field Spectrum (Flat-###.fits) | Contains the spectrum of the (rescaled) flat field (quartz lamp) exposure. (more info) |
| Signal-to-Noise Spectrum (s2n-###.fits) | Contains the signal-to-noise (one sigma) per pixel corresponding to the object spectrum. (more info) |
| Digital Number Spectrum (DN-###.fits) | Contains the count level spectrum for the object. (more info) |
| Type ( filename ) | Description |
|---|---|
| Log file ( hires####.log ) | Standard output from makee. Reports status of reductions and any errors, warnings, or notes. |
| Trace plots ( trace-###.ps ) | Shows polynomial fits to the echelle order traces (row vs. column). (more info) |
| Object profile plots ( profiles-###.ps ) | Shows the profile of the object in each order in the spatial direction. (more info) |
| Skyline shift plots (Flux-###-skyshift.ps) | Shows the residuals of the wavelength scale shift to night-sky-lines. (more info) |
| Final Residuals ( Arc-###-fr.ps ) | ...for arclamp wavelength scale fit... |
| Correlation Functions ( Arc-###-cf.ps ) | ...for arclamp wavelength scale fit... |
