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.ezproxyberklee.flo.org/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
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
