1 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 BGWG blank sky updates Jenny Carter, University of Leicester Andy Read, University of Leicester

2 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 BG_WG_04_05: Selection tool, web based. Sketched out html/CGI script tool. Currently on hold. BG_WG_04_06: Individual users ghosting script. Available for testing through my pages. Needs link/upload to ESAC page Improved ghosting, re-release, add version of exp. maps with those with Jean Ballet flags, re-release files with larger source exclusion region (central residual sources) Sort out Bauer problem Improve selection tools if worthwhile Dataset increase, consider Status at end of last meeting Palermo April 2007

3 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Current status, November 2007 (1) Completed Action Items: AI_EPIC_BG_WG_04_06 – ghosting script now installed on web page. AI_EPIC_BG_WG_05_02 – count rate plots in SSC/PPS energy bands Update of files (events and exposure maps), removing low-E central ring, delivered May Vignetted exposure maps with sources removed for unfilled files delivered May Update of files, corrupt TIME column of refilled event files (FTOOL prob/space?), delivered Aug

4 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Low-E residual sources issue ‘Dodgy’ component observations now removed from some data sets Updated files on web May 2007 e.g. M1 M FF 0.5 – 2.0 keV

5 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Current status, November 2007 (2) Uncompleted Action Items: BG_WG_04_05: Selection tool, web based. Sketched out html/CGI script tool. Currently on hold, suggest disregard (depending on current use). Other plans: Datasets still to be added to increase file size Advice regarding scaling exposure maps to different energy bands – later in presentation

13 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Effects of ghosting/refilled files Query from UG – how to filter out good events that are now, for example in the wrong position spatially in the event file, or how to consider ‘bad’ events that have been ghosted into a ‘good’ area. How many extra bad-flagged events are seen in refilled event files Unfilled NAXIS2 Refilled NAXIS2 NAXIS2 % diff Unfilled next to win/border Refilled next to win/border Unfilled next to bad pixel Refilled next to bad pixel % diff. next to win % diff. next to bad M1 K FF M1 M FF M1 T FF M2 K FF M2 M FF M2 T FF PN K EF PN M EF PN T EF PN K FF PN M FF A PN M FF C PN T FF A PN T FF C

19 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Possible solutions to ghosting problem Masking chip gaps more stringently (good events in bad areas) – already the refilled files are conservatively cleaned Difficult to get bad events out of good areas Ideas? / a limitation to the refilled files and advise on the web page? New ghosting flag?

20 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Exposure map scaling to different E-bands User query – user would like to know how to scale the exposure maps to use in a different energy band Original files created between pimin=200 and pimax=10000 User’s exposure map – own band Blank Sky exposure map – in band pi Blank Sky file scaled to user’s energy band User’s exposure map – in band pi ×=

21 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Scaling exposure maps – testing method Create a Blank Sky exposure map for a choose band and compared to a Blank Sky exposure map in the original band that has been scaled to this choose band If this method is valid, the difference between these two files should be very small Choose band of interest, pi=200 to pi=500 Scale file User file in band of choice User file in band of blank sky files ÷

22 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 BGSelector To replace SelectRADec tool, which selected events within a given search area, on Blank Sky page Currently found at: Can now select on: coordinates, equatorial or galactic, within a search radius revolution numbers within a range exposure times within a range time within a range nH values within a range

26 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Dear Stefano, you wrote: > I associate Prime Partial W2 and W4 to Small Window and Prime Partial W3 and W5 > to large Window, having the same pixel dimensions. In the UHB we are listing only mode names as they are visible in the remote proposal system, too. The W? MOS nomenclature was used in the early phase of the mission and might still be present as header keywords and in SSC products. Please, find below a table of corresponding MOS mode names: Prime Full Window = full frame Prime Partial RFS = refresh frame store Prime Partial W2 = small window Prime Partial W3 = large window Prime Partial W4 = small window free running (not offered) Prime Partial W5 = large window free running (not offered) Prime Partila W6 = full frame two nodes Fast Uncompressed = timing uncompressed Cheers, Matthias Matthias Ehle XMM-Newton SOC User Support Group

27 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Exposure map scaling to different E-bands User query – user would like to know how to scale the exposure maps to use in a different energy band Original files created between pimin=200 and pimax=10000 User’s exposure map – own band Blank Sky exposure map – band pi Ratio – scaling factor Blank Sky file scaled to user’s energy band User’s exposure map – in band pi

29 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Individual queries outstanding Jean Ballet 1.Offset between count maps and exposure maps, MOS. Michael Bauer Skycast and blank sky files. If use attcalc more than once then on using task backscale, the backscale keyword is 0.

30 XMM EPIC MOS Jenny Carter 6 th EPIC BG WG Meeting Mallorca, Nov 07 Exposure map Test with Blank Sky files create and merge exposure maps for test band use pimin=200 and pimax=500 does scaling of the blank sky file give the same result? test by ratio between scaled-bs- exposure map and this band-bs- exposure map, should be 1.0 all over map if scaling procedure perfect. minor differences found differences very small compared to max livetime of blank sky exposure map (in this case 931./251324s)
