BIAS commands for HiRAC

help	Print the BIAS help page.
quit	Exit BIAS. ( alias 'exit' ).
exp [ttt.t]	Normal expose for 'ttt.t' sec.
mexp [ttt[nnn]]	nnn multiple exposures of time ttt.
dark [ttt]	Dark exposure for 'ttt' sec.
mdark [ttt[nnn]]	nnn multiple dark exposures of time ttt.
focus [focus startvalue] [focus stepsize ] [ttt]	Start a focus sequence, each exp. of ttt sec. First image at "focus startvalue" and focus will be incremented be "focus stepsize".
abort	Stop an ongoing integration or readout.
readout	Reads out the ccd. Use 'abort' first to stop the exposure.
addtime ttt	Adds ttt seconds to an integration. 'ttt' can be negative, if the resulting remaining integration time is < 0, the integration is stopped and the ccd is read.
hold	Hold an ongoing integration (close shutter).
resume	Resume an integration. (open shutter).
save	Save the image in next filename.
tint [ ttt.t ]	set default integration time in sec.
mult [ nnn ]	set default no. of multiple integrations.
xbeg [ nnn ]	set start x value of CCD readout.
ybeg [ nnn ]	set start y value of CCD readout.
xsize [ nnn ]	set x size in true pixel value.
ysize [ nnn ]	set y size in true pixel value.
xbin [ nn ]	set x-binning.
ybin [ nn ]	set y-binning.
bin [ nn ]	set x and y-binning.
resetxy	reset the CCD geometry values to defaults.
gainh, gainl	Set gain high or low. Normal operation mode is 'highgain' which gives a readout speed of ~70 sec. for a full frame. 'Gainlow' gives a readout speed of ~45 sec. The conversion factor is different in the two modes.
mpp+, mpp-	Set MPP mode on or off.
autosave+	Turn on automatic saving of images on local disk.
autosave-	Turn off automatic saving of images on local disk.
remsave+	Turn on saving on remote disk. The remote work station and path must be defined in '.biasrc'.
remsave-	Turn off saving on remote machine.
impath [ path ]	Change the default image directory. Use with care.
rempath [ path ]	Set path on remote machine.
remsystem system	Set the remote system ( Unix machine ).
filename [ name ]	Specify the output file names, the length <= 8 char, 1. char must be a letter, last 4 must be numbers. ( Be carefull about this, as the last filename may automatically be updated in '.biasrc'.
autoshow+	Show images in SaoImage.
autoshow-	Do not show images in SaoImage.
ls	Unix list 'ls' command in impath directory.
ll	Unix list 'ls -l' command in impath directory.
imexamine	Start an Iraf-like imex, valid 'imex' commands are: q: back to BIAS commands. z: print 10x10 box values. a: aperture photometry. m: show statistics from data in 'imexbox'. h: histogram plot. c: plot total column. l: plot total line. s: surface plot. e: contour plot. v-v : vector plot from 'v' is hit until next 'v' is hit. u-u : vector plot symmetrically around first 'u'. = : print the plot on the laserprinter. g: Prepare the Tip/Tilt modult to use this star for guiding. p: Preset the T/T guideprobe to the star selected with 'g'.
imexbox [ nn ]	Define the 'aperture' box for surface- and contour plots.
aperture [ nn ]	Set the size of the aperture used in 'imexamine'. The size is adjusted to an uneven value.
magzero [ zz.z ]	Set the magnitude offset for magnitude calculation in the 'imexamine' 'a' function. The value can be fixed at startup in the .biasrc file.
disp [filename]	Display an image from disk in SaoImage. ( alias 'ld' ).
seth [ nnn ]	Set highcut for displayed image. ( alias 'z2' ).
setl [ nnn ]	Set lowcut for displayed image. ( alias 'z1' ).
z+, z-	Zoom in or out, this works independant of SaoImage. If you zoom with SaoImage buttons, the displayed value in the status window is NOT updated.
object [text]	Specify an object name for the FITS header. Max. 20 char. The text is saved untill changed.
comment [text]	Comments to put in FITS header. Max. 40 char. The text is cleared after storing in the FITS header.
comment1 [text]	Extra comment field to put in FITS header. Not cleared after use.
head	View the current FITS file header. Use 'q' to quit.
logon	Start a log of your command screen. Default on.
logoff	Stop the log.
!xxxxxx	Execute the Unix command 'xxxxxx'.
saoimage	Restart saoimage.
Miscellaneous commands	:
sleep nn	Wait for nn seconds. ( for use in batch run ).
wait	Wait for key press.
rbias	Re-read the '.biasrc'.
stat	Ask if camera is Busy or Ready. Answers 'B' or 'R'.
run filename	Run a batch with commands any command ( except this ).
xrun command boxsize	Goes into SaoImage, when Return or Space is hit, the box is saved in a textfile 'command.data'. The command is then run in an xterm window.
guide	Start the tip/tilt fast guiding facility.
sguide	Stop the tip/tilt module.
hfast	Make a indefinite sequence of images with the HiRAC guidecamera. the images are not saved to disk.
habort	Aborts the actions of the 'hfast' command.
ttinit	Initializes the x, y, z, filter and shutter of HiRAC.
xinit	Initializes the x movement of HiRAC. 'yinit', 'zinit', 'finit' and 'sinit' initializes the y movement, z movement, the filter and the shutter.
xgo [nnnnn]	Moves the x motion of the HiRAC guideprobe to position nnnnn (stepvalue). Range is [0..33000]. All of the x,y,z motions has limit switches to avoid mechanical collision.
ygo [nnnnn]	Moves the y motion of the HiRAC guideprobe as above.
zgo [nnnn]	Moves the focus of the HiRAC guidecamera to position nnnn (stepvalue). Range is [0..4400].
telguide+	Turn on autocorrection of telescope when guidestar is drifting out of the T/T stroke range.
telguide-	Turn off the autocorrection of the telescope.
sopen	Direct command to open the shutter. TECH USE ONLY!
sclose	Direct command to close the shutter. TECH USE ONLY!
sexp [nn]	Direct command which opens the shutter for nn seconds and then closes it again. This command has nothing to do with the camera. DO NOT use it for anything else that experiments! It is intended for use when making star trails on the science CCD.
