Full_Name: Kirpal Nandra
Submission from: (NULL) (155.198.204.65)


Could someone please let me know what the correct PATTERN and/or PAT_ID/PAT_SEQ
combination is for diagonal split events (i.e. doubles in which X and Y are both
unequal)? 

I am intending to use these as an indicator of pileup, and a method for
quantifying pileup in pattern-0 only spectra. If anyone has heard of any success
in doing this I would be very interested!

Cheers,

Paul Nandra

The definition of the pattern information is available from the SAS online
task descriptions of packages emevents (for MOS, see Section 'Pattern')
and epevents (for PN, see Section 'Pattern related information').

I am aware of two papers by J. Ballet:
1) in Astron. Astrophys. Suppl. Ser. 135, 371-381 (1999)
2) in ASP Conf. Ser., Vol. 238, Astronomical Data Analysis Software and 
Systems X,  eds. F. R. Harnden, Jr., F. A. Primini, & H. E. Payne 
(San Francisco: ASP), 381 (2001)

Kind regards,
   Matthias

Dear Matthias,

Thanks for your message and especially the references to the Ballet papers.

I should probably have mentioned that I did look in the documentation 
for epevents but the answer to my question is not explicitly there, 
and the documentation is not written in a way which is comprehensible 
to a normal user.

Do you know the answer to my original question i.e. what is the 
pattern number and/or how can I use PAT_ID etc. to select diagonal 
split events?

Thanks,

Paul Nandra

Dear XMMhelp,

I am still awaiting an answer to my question about how to identify 
the pn split events. If someone could give me a response or some idea 
about when to expect one I would be grateful.

Dear XMMHelp,

I am still awaiting a response to my question about identifying  
diagonal split events in the PN, which I submitted now over 1 month  
ago. This is my third followup request - the previous two remaining  
unanswered.

answer to my question, so I am resubmitting the request.
