  4. Obvious or not so obvious • Always credit plots • Consider your venue • Make them for your audience, not so much for you Alycia Weinberger - 26 Feb 2010

  5. My opinion on slide design One good figure will fit on a slide and be worth 1000 words A title helps them understand what you’re talking about A conclusion lets them catch up if they fall asleep Let every slide make a point, and make it clear what this point is. Alycia Weinberger - 26 Feb 2010

  6. Screen Sizes May Not Scale with Room Size V = (screen width / room length) • Astronomy Library • V = 4 ft / 22 ft = 0.18 • Greenwalt Seminar Room • V = 9.25 ft / 45 ft = 0.20 • Marriott Wardman Ballroom • V = 8 ft / 90 ft = 0.09 Alycia Weinberger - 26 Feb 2010

  8. Font Test Slide • This is a serif (Times Roman) font at 32 pt • This is a sanserif (Arial) font at 32 pt • This is a serif font at 20 pt • This is a sanserif font at 20 pt Is one easier to read than the other?

  9. Let’s talk colors • Remember that 5-7% males find Red and Green hard to distinguish/see • Projector vs Screen White CyanGreenRedYellow Orange PurpleBlue MagentaBanana Silver BlackCyanGreenRedYellow Orange PurpleBlue MagentaBanana Silver BlackCyanGreenRedYellow Orange PurpleBlue MagentaBanana Silver Alycia Weinberger - 26 Feb 2010

  10. I’ll Make 2 Points: Conferences sometimes post talks; people will steal your slides Eschew complicated backgrounds HD209458b,HD189733b,XO-1b HD 209458b Mass= 0.69 Mj; Radius = 1.32 Rj; Parent star= G0 Distance = 0.045 AU; HD 189733b Mass = 1.15 Mj; Radius= 1.156 Rj; Parent Star = K1-K2; Distance= 0.0312

  11. Figure Sizes and Whitespace Alycia Weinberger - 26 Feb 2010

  12. Preliminary results • Precision velocity tests… • expected photon-limited precision achieved on short-timescales • statistics hold to better than 3 m s-1

  13. Precision Velocity Tests • expected photon-limited precision achieved on short-timescales • statistics hold to better than 3 m s-1

  14. Inserting Figures in Talks • Other people’s journal figures • Making figures that look good in talks • Making a good JPEG Alycia Weinberger - 26 Feb 2010

  18. Preparing Figures for Papers/Talks You or your colleagues WILL take figures from your papers for talks

  19. 1. Line Thickness: ApJ High Res Moor et al. 2009

  20. 1. Line Thickness: Snapshot from PDF Moor et al. 2009

  21. Font Size for Journal Figures Consider line thickness too Stassun et al. 2008 This axis label as displayed is 12 pt This text is 20 pt

  22. IDL: Postscript vs Vector fonts (16 pt equiv) Thick = 3 Thick = 4 Postscript Times-Roman Default IDL Vector font xthick = 3

  23. Advice for Plotting in IDL (Thanks to Larry Nittler) • Set_plot,’ps’ • plot,x,y,/nodata,xtitle='X Axis',ytitle='Y Axis’ • oploterr,x,y,yerr,3 • oplot,x,y,psym=-4 • device,/close_file

  24. psinit,0 • !p.thick=3 • plot,x,y,/nodata,xtitle='X Axis',ytitle='Y Axis’, charsize=1.5, xthick=3, ythick=3 • oploterr,x,y,yerr,3 • Oplot,x,y,psym=-4 • psterm

  25. Psinit,0 • !p.thick=3 • plot,x,y,/nodata,xtitle='X Axis',ytitle='Y Axis’,charsize=1.5,xthick=3,ythick=3 • oploterr,x,y,yerr,3 • Oplot,x,y,psym=sym(‘cir’,/fill),symsize=1.5 • psterm
