Catherine show that line centroid is good proxy for CTI
- then we can just use that and not worry about XIS CTI metric
- 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)
- Bev & CEG make half-life plots
- 20110324--CEG posted plots to Data Products
Bev check spectra for source contamination
- ALL add paper-appropriate text explanations of data processing to all figures in Data Products
- Eric add PDFs or ADS links to publications
- ALL think about MWB comment about frame-to-frame variations in background effect the FWHM; CI overwhelms the variation;
- Bev has plots of line center and FWHM vs. COR in 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
- CEG will think about equivalent for ACIS, flat FWHM, but are FI wiggles due to background wiggles? compile bkg data in same time bins
- Confirm that ACIS and XIS are using the same high energy reject metric.
- Eric look at literature cited in outline and pull out text (orbital environment, background, describe instruments)
- CEG write text to go with plots in Data Products (instrument, analysis, captions)
- 20110407--CEG a few slides for IACHEC, summarizing our goals and what we're doing IACHEC slides
- 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
