14 Syntax overview tcl: the continuum, line and total spectrum for each energy bin added for all plasma layers of the model. tlin: the line energy and wavelength, as well as the total line emission (photons/s) for each line contributing to the spectrum, added for all plasma layers of the model. tcon: list of the ions that contribute to the free-free, free-bound and two-photon continuum emission, followed by the free-free, free-bound, two-photon and total continuum spectrum, added for all plasma layers of the model. cnts: the number of counts produced by each line. Needs an instrument to be defined before. snr: hydrodynamical and other properties of the supernova remnant (only for supernova remnant models such as Sedov, Chevalier etc.). heat: plasma heating rates (only for photoionized plasmas). ebal: the energy balance contributions of each layer (only for photoionized plasmas). dem: the emission measure distribution (for the pdem model) col: the ionic column densities for the hot, pion, slab, xabs and warm models tran: the transmission and equivalent width of absorption lines and absorption edges for the hot, pion, slab, xabs and warm models warm: the column densities, effective ionization parameters and temperatures of the warm model Syntax The following syntax rules apply for ascii output: ascdump terminal #i1 #i2 #a - Dump the output for sky sector #i1 and component #i2 to the terminal screen; the type of output is described by the parameter #a which is listed in the table above. ascdump file #a1 #i1 #i2 #a2 - As above, but output written to a file with its name given by the parameter #a1. The suffix ”.asc” will be appended automatically to this filename. Warning: Any existing files with the same name will be overwritten. Examples ascdump terminal 3 2 icon - dumps the ion concentrations of component 2 of sky sector 3 to the terminal screen. ascdump file mydump 3 2 icon - dumps the ion concentrations of component 2 of sky sector 3 to a file named mydump.asc.
2.3 Bin: rebin the spectrum 15 2.3 Bin: rebin the spectrum Overview This command rebins the data (thus both the spectrum file and the response file) in a manner as described in Sect. 2.6. The range to be rebinned can be specified either as a channel range (no units required) or in eiter any of the following units: keV, eV, Rydberg, Joule, Hertz, Å, nanometer, with the following abbrevations: kev, ev, ryd, j, hz, ang, nm. Syntax The following syntax rules apply: bin #r #i - This is the simplest syntax allowed. One needs to give the range, #r, over at least the input data channels one wants to rebin. If one wants to rebin the whole input file the range must be at least the whole range over data channels (but a greater number is also allowed). #i is then the factor by which the data will be rebinned. bin [instrument #i1] [region #i2] #r #i - Here one can also specify the instrument and region to be used in the binning. This syntax is necessary if multiple instruments or regions are used in the data input. bin [instrument #i1] [region #i2] #r #i [unit #a] - In addition to the above here one can also specify the units in which the binning range is given. The units can be eV, Å, or any of the other units specified above. Examples bin 1:10000 10 - Rebins the input data channel 1:10000 by a factor of 10. bin instrument 1 1:10000 10 - Rebins the data from the first instrument as above. bin 1:40 10 unit a - Rebins the input data between 1 and 40 Å by a factor of 10. 2.4 Calculate: evaluate the spectrum Overview This command evaluates the current model spectrum. When one or more instruments are present, it also calculates the model folded through the instrument. Whenever the user has modified the model or its parameters <strong>manual</strong>ly, and wants to plot the spectrum or display model parameters like the flux in a given energy band, this command should be executed first (otherwise the spectrum is not updated). On the other hand, if a spectral fit is done (by typing the ”fit” command) the spectrum will be updated automatically and the calculate command needs not to be given. Syntax The following syntax rules apply: calc - Evaluates the spectral model.
