Update on refinement of the PSF

- Spectral and spatial studies involving EPIC data from

- MCG-6-30-15

- 3C 273

XMMEPICMOS


MCG-6-30-15

Rev 0301 – SW M-filter - 82.0 ksec – some low-level flaring

Rev 0302 – SW M-filter - 123.5 ksec – clean (a few small flares)

Rev 0303 – SW M-filter - 125.0 ksec – very clean indeed !!

Bright point source – not too piled-up

ON-AXIS

-Analysis of King Profile PSF in CCF

- Core Radius R0 and slope alpha show strong energy dependence

APPROACH 1

- Redo entire spectral analysis using altered King profiles with various R0-E and Alpha-E dependencies

- Initial results suggested a far flatter energy dependence is required

PSF=CCF(KING)

XMMEPICMOS


MCG-6-30-15 APPROACH #1

- Exploration of parameter space in King profile R0- and Alpha-dependence

--- Alter CCF files (XPSF, extension 70 [King], just on-axis values)

--- Redo entire analysis (3 observations, 3 instruments, 8 spectra/ARFs)

--- Re-alter CCF files (XPSF) and repeat…

- Number of these searched-for (S) PSF dependencies give good results

e.g.

MOS1 R0=4.5 (constant with E) alpha=1.45-1.36 (decreasing with E)

MOS2 R0=4.5 (constant with E) alpha=1.45-1.36 (decreasing with E)

PN R0=5.0 (constant with E) alpha=1.65-1.38 (decreasing with E)

…(also more complex dependencies can give even better results…)

MCG-6-30-15 APPROACH #2

- Data of sufficient quality to calculate PSFs in small energy bands

- Development of software to fit King profiles to images

- See how these King profiles compare to those in the CCF

- Use these King profile PSFs in the spectral analysis

Calibration of the PSF

Large number of bright source observations

Only specific range of radii allowed – pile-up at small R

- statistics/window size at large R

Stack the observations on to one-another (keeping good R range), to build a

good 2-D representation

Problems: normalising the maps w.r.t. each other

very different count rates per frame

different exposures, levels of OOT events
