How To Access Your HET Data
Current Science Operations Data Access
To access your data you will need to acquire a login to the TACC and once that login is confirmed you will need to contact the HET Science Operation Supervisor (shetrone(at)astro.as.utexas.edu) and let him know which Program you are a Co-I in and what your TACC login is. Once your TACC login is linked to the HET project at the TACC you will have to wait for the TACC human approval to take place, this usually takes less than 48 hours.
To collect your data you will need to login to maverick.tacc.utexas.edu using this login then cd to where the data is located: /work/03946/hetdex/maverick/YYYYMMDD where YYYYMMDD is the directory where the data is stored in UT date. Note that the night report is in civil date for the start of the night and the data is stored by UT date.
The directory structure in each nightly working directory is the instrument name, then the shot/observation number for that set, then the exposure number within the shot/observation.
Example: 20160401/lrs2/lrs20000001/exp01/lrs2 for lrs2 data
All of the setup images are stored in the directory acm in the same nightly working directory as the science data. The images names are date stamped so look for the image taken just before an observation began. In the near future we will be generating a tar file with the setup images for each observation and those will be located in the same level as the expXX directories.
Example: 20170401/acm/20170401T233957.4_acm_sci.fits for acquisition images
To associate the position of the fiber head of the instrument you are using with the ACM image please see the appropriate regions file for that instrument:
All of the guider images are stored in the directory gc1 or gc2 (there are two guiders) in the same nightly working directory as the science data. The images names are date stamped so look for the image taken at the same time as your observation. In the near future we will be generating a tar file with the guider images for each observation and those will be located in the same level as the expXX directories.
Example: 20170401/gc1/20170401T000052.4_gc1_sci.fits for guider 1 images
Example: 20170401/gc2/20170401T000049.5_gc2_sci.fits for guider 2 images
Future Science Operations Data Access
During full (future) science operations a PI or co-I can access their data through HETwise which is current still under construction.
How to Access old (pre-2014) HET Data
Upon acceptance of your project by the HET staff, you will be given an
ftp account for retrieving your data from the data server in Austin.
For illustration we will give an example of retrieving data
for the project UT02-2-004. This project has been provided with the login
name of schwartz and the password of Sponge. The PI has been
notified by the HET staff that she has data from the night of October 31, 2002
UT (20021031). The commands used to retrieve the data using the
standard Unix command line sftp program are listed to the right in the table
|sftp to hydra.as.utexas.edu
|| sftp firstname.lastname@example.org |
|use the provided password
|| Sponge |
|cd to the directory that is named the same as your
|| cd /het_data/het_users/UT02-1-004 |
|cd to the data directory named for the UT observing
|| cd 20021031 |
|set sftp to binary mode
|| binary |
|get all the data
|| mget * |
|cd to the calibrations directory
|| cd /het_data/het_users/calibrations |
|cd to the data directory named for the UT observing date
|| cd 20021031 |
|get the README file describing the available calibration files
|| mget README.* |
|get all the files needed to calibrate your data
|| mget * |
|| bye |
When you are notified that new data are available, the e-mail message
should give a description of the contents of the files taken for your
project. If there are any questions about the data, calibrations, or
anything to do with the observations, please send an e-mail
to the Resident Astronomers.
If there are any problems with the ftp system (including lost or forgotten
passwords or account names), please contact Jim Fowler.
