Name
copymon --- copy incoming ESI, HIRES, and LRIS images into the
current directory
Usage
copymon instrument
Parameters
- instrument
- name of the instrument being used. Possible values are
ESI, HIRES, and LRIS.
Description
copymon automatically copies incoming ESI, HIRES, or LRIS
images from the datataking system's output directory into the
current directory. The user can start this script running in
the afternoon and allow it to run all night (it terminates
automatically after 10 a.m.). This frees the user to worry
about reducing the images rather than having to manually check
for new incoming images and copy them over.
The ``Save the Bits'' archiving system now in operation at Keck
will not archive images which have been manipulated by IRAF in
any way (including those which have been copied using the
imcopy task). Hence, it's important for observers to
leave their raw LRIS images untouched. For observers who must
do some quick data reduction (overscan subtraction, flat
fielding, spectral extraction, etc.) the best option is to copy
the images from the data collection machine (manuka) to a
scratch disk atatched to the summit data reduction machine
(pelekane). The copymon script offers a hassle-free
way to do this.
Examples
- An LRIS observer using the lris1 account wants
to analyze images on pelekane, the summit data
reduction computer. First, the observer checks to see which
scratch disks are attached to pelekane by logging
in to that machine and issuing the df command:
> df

/dev/dsk/c0t12d0s5 8358858 3840651 3682327 52% /scratch102
...
The observer selects /scratch103 and
creates directory
/scratch103/lris1/05aug98. The user then
logs into manuka, the LRIS datataking
computer (this is required for copymon to
interact with the datataking system). After issuing
the cd command to go to that directory, the
observer starts copymon running using the
following command:
copymon lris
The program starts up and prints:
copymon is now running! Incoming lris files will be copied
into the current directory (/tmp_mnt/s/scratch103/lris1).
This program will terminate automatically in 18 hours or at 10 a.m.,
whichever comes first.
The program can be allowed to run until quitting time,
or may be stopped with repeated Ctrl-C
interrupts when shutting down for the night.
Notes
- copymon may only be run on the instrument
datataking computer. For ESI this is kanaha,
for LRIS this is punaluu,
while for HIRES this is nuu.
