Other command-line tools used often

9 - dmhedit

12 - The data reduction tools, *_process_events, tg_resolve_events, and the like.

15 - mkrmf, mkarf, dmextract

18 - mkarf, mkgarf, dmextract, tg_resolve_events, acis_process_events, tgextract

     I use slang, but as embedded in isis.

19 - dmextract, mkrmf, mkarf, merge_all.  I don't use psextract
     because it does some things wrong and does many things in an
     undesirable way (e.g. it provides no options for binning background
     spectra but uses a default, entirely useless binning of 1:1024:20).

21 - dmextract, mkrmf, mkwarf, dmhedit, mkeypar (and related tools)

22 - dmextract, wavdetect, mkexpmap

23 - reproject_events, dmmerge, dmhedit, acis_process_events, 
     acisreadcorr, destreak, dmimgcalc, dmstat, plist, pset.

24 - mkarf and the apply_acisabs correction
     acis_process_events

25 - destreak
     dmcoords
     acis_process_events
     dmextract
     dmhedit
     dmregrid
     mkexpmap
     mkinstmap
     mkwarf
     mkrmf

27 - Not clear what this means. I'll use any unix cl commands; idl and ftools for
     astronomy-specific work; isis for spectral analysis; I am learning how
     to use S-lang, too.

30 - dmextract,mkarf,mkwarf

32 - apply_acisabs, acisspec

33 - mkgarf, mkarf, mkrmf, mkinstmap, mkexpmap, asphist, dmextract,

43 - acis_process_events, tg_*, fullgarf (asphist, mkgarf, dmarfadd)
     isis, s-lang, as embedded in isis, isis-script for custom command-line
     isis utilities.

47 - acis_process_events, mkarf, mkrmf, destreak, dmregrid, etc, etc
