Common block `ewout'

A feature added September 2007 is output of the strongest lines, sorted by element and ion into a common block called 'ewout' This feature is only available for the warmabs, photemis, hotemis, hotabs models (not windabs, or multabs). The contents of the common block are:

lmodtyp: identifies which model most recently put its output into the common block. lmodtyp=1,2,3,4, where 1=hotabs, 2=hotemis, 3=warmabs, 4=photemis

newout: number of lines in the list. This is zeroed after each call to warmabs, photemis, hotabs, etc.

lnewo: array conatining line indexes. These should correspod to the line indexes in the ascii line lists on the xstar web page.

kdewo: character array containing the name of the ion

kdewol: character array containing the name of the lower level

kdewou: character array containing the name of the upper level

aijewo: array containing A values for the lines

flinewo: array containing f values for the lines

ggloewo: array containing statistical weights for the lower levels

ggupewo: array containing statistical weights for the upper levels

elewo: array containing the line wavelengths

tau0ewo: array containing the line center depths

tau02ewo:array containing the line depths at the energy bin nearest to line center

ewout: array containing line equivalent widths in eV, negative values correspond to emission

elout: array containing line luminosities in xstar units (erg/s/1038)

The details of how to get at the contents of the common block are up to the user. Currently xspec does not have a mechanism to do this, but it is straightforward to write a small fortran code to call the models with suitable parameter values and print the common block from there. The calling sequence for an analytic model is described in the xspec manual. It is important to point out that the common block is overwritten at each call to one of the models, so it should be emptied by the calling program after each call to one of the models.

An example is as follows:

      program fphottst
c
      implicit none
c
      real ear(0:20000),photar(20000),photer(10000),param(30)      
      integer ne,mm,ifl
      real emin,emax,dele
c
      ne=10000
      emin=0.4
      emax=7.2
      dele=(emax/emin)**(1./float(ne-1))
      ear(0)=emin
      do mm=1,ne
        ear(mm)=ear(mm-1)*dele
        enddo
      write (6,*)ear(1),ear(ne),ear(ne/2)
      param(1)=2.
      param(2)=-4.
      param(13)=100.
      param(12)=0.
      param(3)=1.
      param(4)=1.
      param(5)=1.
      param(6)=1.
      param(7)=1.
      param(8)=1.
      param(9)=1.
      param(10)=1.
      param(11)=1.
      param(3)=0.
      call fhotabs(EAR,NE,PARAM,IFL,PHOTAR,PHOTER)
