Calculation of the Point Spread Function Probability or Quantile

 

Two models are available for ROSAT PSPC and HRI point spread function, a Gaussian and an Analytic model.

CALCULATE/PSF distr [INFO_P_Q_flag] [param] [misdet] [attitude]
  The parameters depending on the distribution are listed in Table 5.17.

   table4132
Table 5.17: PSF-distribution dependent parameters to be specified for flag settings flag=P[robability] and flag=Q[uantile]

The model result is written to the keyword array OUTPUTD as given in Table 5.18.

Examples are:

CALCULATE/PSF  Gauss     P  50,10,100
CALCULATE/PSF  Analytic  Q  50,10,0.9
CALCULATE/PSF  Analytic  P  50,10,100
CALCULATE/PSF  Gauss     P  50,0.,1200.,100  attitude
