TV6 cheat sheet
A personal list of TV6 commands. DS
-
expt=<n>
set exposure time to <n> seconds
-
move im0=imb
collect a background image in buffer im0
-
move im1=ime
collect a CCD image
-
move im2=ime
collect a second CCD image
-
move im3=im1:im2 dzinger
-
move im4=im3-imb subtract
background
-
move im5=im4!imi
flat field correction
-
move im6=im5!imd distortion
correction
-
move ima=im6
autosave file
The whole series of commands can be combined into a macro using the
"auto" command:
-
auto <cmd1>;<cmd2>;<cmd3>; ...
Files containing the flat field and distortion corrections for the 1k detector
are
-
c:\perm\i1kbin1.tif
flatfield correction for 1x1 binning
-
c:\perm\x1kbin1.tif
distortion correction, x coordinate, for 1x1 binning
-
c:\perm\y1kbin1.tif
distortion correction, y coordinate, for 1x1 binning
Files for 2x2 binning have corresponding names. Since binning is done before
digitization
of the charge, going from 1x1 to 2x2 increases the read-out time and
reduces the read-out noise.
Pixel size of the 1k detector is 50.8 micron x 50.8 micron.
The files are imported into TV6 by
-
setint <flatfield>
-
setdist <x distortion> <y distortion>
Binning can be changed by
-
hbin=<n>
n integer, n=1,2,3, ...
-
vbin=<m>
m integer, m=1,2,3, ...
