Jenny's PAW notes

It seemed a good idea to write my notes from misc bits of paper onto a web page so I could always find them.

Thanks are due to all who have taught me PAW stuff - mostly Roger and Frank.
 

Resizing the default PAW window Usage: want 1col by 3 rows, but without the default wide-screen formatting of PAW. Params to change: set xsiz  nn set ysiz  nnn To decide that nn and nnn should be, use: > SET at the PAW prompt to see what the default settings are. My settings currently do: parameter | current value | default value | explanation -------------------------------------------------------------- XSIZ | 21.00 | 20.00 | Size along X YSIZ | 29.70 | 20.00 | Size along Y

Directories Open file with, say: > h/fil 1 uds.hbook Then want to change into subdir nanohists: > cd nanohists Then want to get back, need that lun id number that you opened the original hbook file with, and do: > cd //lun1

Picture printing (good idea to put this in pawlogon.kumac) >opt zfl1 Then make your picture. Then >p/print file.eps The extension you give in the picture-print command is the file-type it'll give you as output.

Handling files with upper cases in their names (Should put this in pawlogon.kumac!) > kuip/s/filecase KEEP

That stats box Turn it on with opt stat options 111111 (see PAW manual) Turn it OFF with opt nstat

To have rotated text set tang 90 //set text angle text x y 'tex' 0.3 //position, position, text, size set tang 0 //best to reset it Get a full list of available commands set

Generating the common block nt/uw 1013 includefile.file

Random useful bits m/clr clears the screen. Or just clr. m="misc" If the command is unambiguous, don't have to put the initial bit, as in clr Closing files: f/close lunID close lunID //cos the command is unambiguous Random fitting commands I can use sometime: h/pl 580 //pre-existing histo v/cr par(10) //?? - new vector called 'par' with 10 zero slots h/fit 580 g+p2 //Gaussian plus quadratic h/fit 580(10:30) g //which bins plus Gaussian

Saving multiple plots to a single PS file Can do from normal PAW prompt: f/file 66 temp.ps metafile -66 -111 exec plotmakingkumac metafile 0 close 66 Note that the plots (probably) won't appear on screen - but they will be made - check temp.ps

Finding the number of entries in part of a histogram E.g. for histo 505, want to know how many entries up to 1.8 GeV. 1.8 GeV is the lower edge of bin 71, so want to count the number of entries in bins 1-70: h/pl 505 v/cr c(100) | same number of bins as in histo get/conts 505 c v/prin c | print the contents of each bin in c sigma c=sumv(c) | overwrite c with cumulative sum of bin contents v/print c(70) | contents of bin 70, else could just print all and look
