| IA |
0: print only on screen if ITV=1 (see LINE.DAT) 1: write instrumental profile to FOR003.DAT 2: write spectrum to FOR003.DAT 4: make lineprinter plot of spectrum in FOR003.DAT 8: write spectrum to PLOT.OUT |
| NSPAC | continuum level for lineprinter plot -- usually 100 |
| EXPAND | expansion factor for details in lineprinter plot -- usually 5 |
| XIMAC | macroturbulence ximacro [km/s] -- can be overridden in LINE.DAT |
| LIMA |
0: no instrumental broadening -- see also LINE.DAT >0: explicit (measured) instrumental profile available <0: use "standard" profile |
| ORD(I) | order number |
| LIM(I) | central wavelength [Å] of order #ORD(I) |
| MO | order number for which instrumental profile follows |
| LO | wavelength of instrumental profile |
| if LIMA > 0: | |
| IMAX | number of profile points |
| LAP(I) | wavelength of profile point |
| PAP(I) | profile at LAP(I) |
| if LIMA < 0: | |
| LOFWHM | full width at half maximum of order MO at wavelength LO,
FWHM = LOFWHM·MLAM/LO·MO/M, with MLAM != observational wavelength and M: order of observations |
| STR | stray light contribution |
| I |
