Submission from: (NULL) (128.138.140.161)


I just checked the observation log summary and I see that the observation was
executed during revolution 0626.  But I see an alarming message saying "Slew
failure. On target at 2003-05-10@12:46:00. Observation affected by high
radiation."  What does this mean?  Was the observation a total failure?  If so,
will it be repeated, and when?  If not, when will I be able to see the data? 
There is nothing listed on the status of the data.

Thanks a lot!  Dick McCray

Dear Dick,

 let me first reassure you: the observation was **not** a failure.

 The first message ("Slew failure ...") simply tells you that the
start of the observation was delayed with respect to the expected.

 The second message ("Observation affected ...") tells you that
the level of particle background across the observation elapsed
time was sometimes larger than the quiescent level. The detailed
imapct on the scientific quality of your observation can be
evaluated only after a detailed scientific analysis of the data.
You can, however, broadly evaluate the scientific impact by
looking ay the last column of the observation log, which reports
the net exposure time for each exposure. From this column, you
can derive that the observation had ~104 ks, ~107 ks, and ~113
ks exposure time in the MOS, pn, and RGS cameras, respectively.
Observations are automatically qualified for repetition, if
this number is lower than 80% of the approved time for the prime
instrument, and 60% for the others.

Matteo, thank you very much for the good news!

When will I be able to see the data?

Dick

Dear Dick,

 typically, data are shipped to the PI after 1 month the observation
was performed. Have a look at:

http://xmm.vilspa.esa.es/external/xmm_news/mission_status/20030331/images/cd_delay_sm.jpg

 Every PI is automatically notified via e-mail, when ODFs and PPS
products are available for retrieval in the science archive.

 Regards, Matteo

Matteo, thanks again for the prompt reply.  We'll plan to get started
analyzing the data in mid-June.  This is exciting!

All the best, Dick
