Exgal Formaldehyde VLA Observation Summary

Archive Extraction and Download

All data can be extracted from the EVLA archive available from the NRAO User Portal. Since these data sets are extremely large, one needs to use the CV lustre to both store and process (with CASA) these data. Steps to extraction and download are:
  1. Make the archive extraction request from NRAO User Portal, and wait for the data to be extracted into the archive directory.
  2. Login to jmangum@cvpost-master.cv.nrao.edu to request a lustre (cvpost) node: ssh jmangum@cvpost-master.cv.nrao.edu
  3. List all used and free lustre nodes: qstat -a.
  4. Request a node: nodescheduler --request 45 1 to request one node for 45 days (the current maximum), for example. You will get an email telling you which node you have been assigned. Let's assume in the following that you have been assigned "cvpost005".
  5. ssh into your assigned node: ssh cvpost005
  6. If you are going to use a VNC connection later, start the VNC server: vncserver
  7. cd to your data directory (you should have already been given a login on the lustre). NOTE: Data directories are something like /lustre/naasc/jmangum.
  8. Use the following wget command to copy files from the archive:
wget -b -e robots=off --wait 1 -rc -nH --cut-dirs=1 --header="accept-encoding: gzip" --user=Chicken --password=Butt https://archive.nrao.edu/secured/Chicken/

  • If you are copying files from the public archive, use the following command (use wildcards on the MSNAME if necessary):
wget -b -e robots=off --wait 1 -rc -nH --cut-dirs=1 --header="accept-encoding: gzip" ftp://ftp.aoc.nrao.edu/e2earchive/MSNAME

UPDATE NOTES:
  • 2014-01-02: Updated for all measurements made through projects 11B-026, 12A-067, 13A-178, and 13B-113 observed to-date (i.e. including everything except an anticipated 13B-113 NGC253 SB). Double-checked all observed SBs with listings for each galaxy.

NGC253

Session Log
Project Date Array Band Targets SBID Duration (hrs)
11B-026 2012-01-21 DnC Ku NGC253 4982259 2.5

Comments: Only 16 antennas available with Ku-band receivers. Extracted from archive and located on multivac04 at /.lustre/naasc/jmangum/NGC253. Ed ran these data through the beta version of the EVLA pipeline and produced the images in /export/lustre/jmangum/NGC253.

Edit: Appears to have 18 available antennas

12A-067 2012-05-19 C C NGC253 9248494 1.5
Comments: Extracted from archive and located on multivac04 at /.lustre/naasc/jmangum/NGC253. Note that CASA spit out an error during archive extraction, so be careful when processing these data.
2012-06-22: VLA staff found an error in the online flagging system which incorrectly applied some online flags. This data set is the only one in project 12A-067 that is affected by this error. Re-extracted MS and downloaded it on multivac04 at /export/lustre/jmangum/BJ0401. Extraction did not produce a CASA error this time (so the previous error must have been due to the flagging problem identified). Rachel found that these newly extracted data were significantly cleaner than the flag-flawed version. For example, the newly extracted data did not have the problem which caused the first 10 seconds of each scan to be bad.
13B-113 2014-01-24 BnA C NGC253 25319659 2.0
Comments: Pipeline processed on 2014-01-27. Requested pipeline processed MS and associated files. Drew placed files in archive location and I started download on 2014-01-27. Files located at /lustre/naasc/jmangum/NGC253/DO1316.
