using fakeit

Hey all,

so the default on fakeit is to load in an arf and an rmf and then a function. 
I have 2 questions.

1.) when i use fakeit (with a  function and parameters that I already used to 
fit data) nothing comes out. I just get a straight line. I'll put the code 
below:

load_arf("/export/lecanard/6601/combined/6601_HEG_1.arf");
load_rmf("/export/lecanard/6601/rmf/acis_1.0_HEG_-1_rmf.fits");
assign_rmf(1,1);
assign_arf(1,1);

require("xspec");
fit_fun("phabs(1)*pcfabs(2)*diskbb(3)");

set_par("phabs(1)", [2.683428 ]);
set_par("pcfabs(2)",[2.711441 ,0.6840924]);
set_par("diskbb(3)",[52.20151 ,1.897251]);

fakeit;
plot_unit("kev");
plot_data_counts(1);


2.) Eventually what I would like to do is just take the model that I had 
before and extend it to cover wavelengths that my data can't see...(up to 
about 25 keV).  However, if I put in an arf I'll just be cutting the effective 
area away to match what I already have. Can fakeit do this or should I look 
for other avenues?


Thanks,
Bert
