Startup of BCSpec
- At the telescope:
- In the control room on the "bok" computer:
- Log into the bokobs account. The password is located on the whiteboard
in the control room. If this is the first night of your observing run, it
is highly recommended that you reset the bokobs account to delete data files
placed on the disk by previous BCSpec users. During your run, be VERY careful using the reset bokobs command. Make sure that you have archived all of your data on another machine, data tape, CD, and/or DVD since resetting the account will
DELETE all of your data on bok. If you decide to change the bokobs password, make sure that you accurately record the new password on the whiteboard in the control room.
- In a terminal window, start the Opto22 server by typing
- In another terminal window on bok, start the data server by typing
CAUTION: Make sure that there are no ds9 display
windows on the desktop before staring the dataserver script. The script
will create a ds9 display window for you and this is where your CCD exposures
will be automatically displayed.
- In the control room on the "bokccd" computer:
- Start AzCam by clicking on
the "StartBCSpec" icon on the bokccd desktop.
- You can now use the main control panel of AzCam to set
data storage paths, detector parameters, selected image header values, and acquire data. The AzCam system is quite intuitive and its
User's Guide (PDF Version) offers a good overview of its functionality.
- Observers typically set the data storage path so that
images are transferred to the 'bok'
computer. However, one is able to write images to a directory on 'bokccd' instead. This option is especially useful in the event that you are experiencing
network communication problems between the two machines.
NOTE: Generally, the instrument and data acquisition are
controlled from the bokccd keyboard and mouse, while images are saved,
displayed, and manipulated by the observer on bok.
Observers have the option
of displaying the bokccd desktop on bok and therefore controlling
all aspects of the instrument and data collection using the bok
keyboard and mouse. To do this, type: vncviewer bokccd in a
terminal window on bok. You will be asked for a password which
is simply the name of the computer whose desktop you wish to display
(all lower case). One can resize the vncviewer window as desired, but be
aware that this window will not update AzCamTool exposure and readout countdown clocks
in a way that even remotely approximates "real time".
These updates are much faster on the bokccd display.
