Draft paper to Mark by Friday, Nov. 17
We should talk about the mechanics of writing the paper. Does Eric keep a master copy and we send text and revisions to him? Do we post a master copy here that we can check-out to edit ourselves?
- Eric will keep master version of tex file, update wiki on occasion
- Bev and Catherine can borrow tex tarball for big jobs
- Catherine's Suzaku poster wishlist:
- Peak & FWHM vs COR for early (CI off) and late (CI on) for XIS1 and XIS3 (Thank you Bev!)
- Catherine work out an analytic model (what does all this mean?!?)
- Catherine send paper appropriate figures to Eric
- Catherine send to Bev copy of her line fitting (20110607, and the forgotten bits on 20110620)
- Catherine show that line centroid is good proxy for CTI (20110621--CEG posted to Data Products)
- then we can just use that and not worry about XIS CTI metric
- Catherine spot check line fits (20110621--CEG convinced that results are consistent between different bkg levels and src count rates)
- Catherine convince herself that ACIS QE drop goes away with CTI correction (20110622--mostly goes away. QE drop goes from ~12% to ~3% over 11 years)
- Catherine find the cut-and-paste text from previous ACIS papers, send to Eric (20110705--sent some text from SPIE2007 paper)
- Catherine make half-life plots
- 20110324--CEG posted plots to Data Products
- Bev find the cut-and-paste text from previous XIS papers, send to Eric
- Catherine make XIS half-life plots using Bev's data which use Catherine's fitting method (20111018)
- ALL think about MWB comment about frame-to-frame variations in background effect the FWHM; CI overwhelms the variation;
- Bev make new plots of line center and FWHM vs. COR using Catherine's fitting method
- from 2008 paper, will look for script that made them and verify that it's still flat; revisit with non-XIS2 devices
- 20110504--bev posted xis1 & xis3 plots for 201101 to Data Products
- Catherine will think about equivalent for ACIS, flat FWHM, but are FI wiggles due to background wiggles? compile bkg data in same time bins
- 20110816--actually confirmed this a while ago and forgot to update, the FI wiggles are not correlated with the background, ACIS FWHM is not strongly sensitive to sacrificial charge
- Bev confirm that ACIS and XIS are using the same high energy reject metric; time units and spatial area? what is being rejected on-board?
- XIS uses only cal source area, ~ 9-10% of full 1024x1024
- Bev rejects summed event PHA of >= 3750 on ground to match ACIS rejection; but some single pixels are rejected on board XIS, possibly below 3750
- seems no way to compare XIS rejection to ACIS
- also dependence on input energy spectrum
- Bev will look for XIS frame data to see how well the background metric matches that of ACIS
- Bev will grab raw frames for the paper to show background, and bias-correct; XIS BI & FI, CI on & off, ACIS BI & FI
- Eric look at literature cited in outline and pull out text (orbital environment, background, describe instruments)
- Eric begin latex document for A&A (downloaded A&A template)
- Bev and Catherine send Eric paper-appropriate text explanations of data processing to all figures in Data Products
- Eric add PDFs or ADS links to publications
- Eric maintain action items page
- Catherine and Bev look for pictures of ACIS for schematic
- Eric edit ACIS schematic to add cal source regions
- Eric look for pictures of XIS for schematic
- Eric look into A&A photo and color policies
- Eric look into figure format (titles, fonts, etc.) policy
- ALL think about whether to include trailing charge info for both instruments
- not very fruitful; XIS is limited to the top of the array, so hard to separate trailing charge from normal event splitting; also SCI will complicate this
- Catherine. Look at Bev's plots (http://space.mit.edu/XIS/monitor/ccdperf), get a sense how ACIS would look on the same kind of plot. Qualitatively, how much does trailing charge matter.
- Bev make gain/FWHM vs. COR plots for XIS3, Oct+Nov 2006
- see if it's as good as XIS2 previous plots
- send data to Catherine for paper figures (done 10/28/2011)
- Eric change fig captions for gain/FWHM vs. COR; data are for ~ 1 month (or 2) straddling CI turning on, and for XIS2 (or XIS3)
Completed Action Items
- ALL have an outline for Mark
- outline is sent to Mark (2011-01-28)
- here is a link to an attachment: Outline PDF
- 20100210--comments from Mark here
- Eric combine outlines
- Eric convert action items page
- ALL decide on common CTI metric (which grades, which pixels in island, which rows)
- use center pixels
- XIS cal source regions-
- both use all telemetered grades (minus 255 for XIS, minus 5 Bev grades for ACIS, S3 only uses g02)
- Bev will try restricting grades, esp. for BI
- 2011-05-05 decision to not pursue CTI metric for XIS
- Bev make CTI plots for XIS upper rows (1 month bins)
- 20110210Bev has IDL script set up, pixel fits (center pixel pulseheight and trailing pixel) are working for all detectors/quads, CTI calculation is not working completely
- Catherine replicate same plots for ACIS, pending Bev's results
- 2011-05-05 decision to not pursue CTI metric for XIS
- Catherine replicate existing Bev plot (monthly plots of FWHM, summed pulseheight centroid)
- 20110210--CEG has framework set up, waiting on flaky disk
- 20110217--CEG posted plots to Data Products
- 20110407--CEG made plots for IACHEC, For paper, want just combined plots, peaks (eV)/5894 eV – same y-range, widths in FWHM (eV)
- Eric add space for Leaky Buckets presentations (posters, talks slides) to Publications page (20110620--CEG)
- 20110407--CEG a few slides for IACHEC, summarizing our goals and what we're doing IACHEC slides
