Directions for Phase 2 Submission
GALEX GI Program, Cycle 2, Starting 1 October 2005
PIs of accepted proposals (not archival proposals) should have received a template for submitting Phase 2 information. Many of the fields have been prefilled for you from your Phase 1 information (for reminders on the fields, see information shown below). Note that disallowed targets (listed in "Additional Comments" section of the peer reveiw report) have not been removed. This will be the PI's responsibility. Please read carefully the steps shown below.
SAMPLE XML template files for Phase 2 may be found at http://galexgi.gsfc.nasa.gov/Cycle2/Phase2/index.html
After you update the template, you should check it using the validation tool, also at http://galexgi.gsfc.nasa.gov/Cycle2/Phase2/index.html and make any corrections needed.
Submit the final, completed Phase 2 template by emailing it to
Please note the following while revising your Phase 2 template.
0. It is the PROPOSER'S responsibility to verify the observation information. Please pay particular attention to the target information. It is the PROPOSER'S responsibility to specify observations that are safe for the instrument. Observations will not be repeated for errors that are the proposer's.
1. Targets will only be accepted after 1) a successful Phase 2 submission and 2) a safety check by the SODA (Science Operations and Data Analysis team at Caltech. Unsafe fields may be rejected by the SODA team without further work on their part. Please check your targets against the brightness checker and Zodi background checker at http://galexgi.gsfc.nasa.gov/tools/index.html. If you have questions or need help, send email to email@example.com
Note: (8/24/05) If you have brightness limit concerns, here is the latest information. FUV limits remain the same. Observations are being performed that will determine what the NUV bright source limit will be. When preparing your xml file, submit as much information as possible (the science target position is critical, possibly a small table of brightest stars in field) and mission planning will work through GALEX GI Helpdesk Team to get your targets through Phase 2. Please read the BRIGHTWAIVER information below as well.
2. If targets were disallowed as described in the "Additional Comments" section of the peer review report, proposers should remove them from the target list. Please do not renumber your targets after removing disallowed targets.
Information about the Phase 2 template fields
PROPOSAL AND GI IDENTIFICATION: Identifying information (<nasapropno>,
OBSERVATIONS: Please check carefully and update as necessary. These are organized one observation at a time. An imaging observation and a grism observation of the same target are two different observations and each needs an independent entry. Repeated observations of the same target are two different observations and each needs an independent entry. Multi-orbit integrations of the same target count as a single observation; this includes grism observations at different orientations on the sky.
Comments about individual tags:
TARGNO: Do not change. If you are adding new observations (e.g. grism pre-images) enter "NEW". Phase 2 checking / submission software will assign <targno> for new targets.
PRIORITY: Rank each target's priority to your program. 1/3 of your targets should be priority 1 (high), 1/3 priority 2 (med) and 1/3 priority 3 (low). If you only have one target, make it priority 1. This parameter is added to mitigate the effects of, for example, possible unexpectedly low GALEX observing efficiency. It does not have anything to do with the likely observing order of your targets. Note that the priority tags are initially empty; you must fill them in. If you don't set your priorities, or do not divide your priorities evenly between 1,2,3, we will assign them all to priority 3.
OBJECT NAME: Please use IAU conventions for target names, in the <objectname> field. (Information on IAU conventions at:
<ra> <deg> 12.4567 </deg> </ra>
<ra> <deg> 47 </deg><min> 19 </min><sec> 19.9 </sec></ra>
POSITIONS: Note that you must include at least two positions:
SCIENCE TARGET SIZE: You will need to add a size (~diameter) in arcminutes, for each target of scientific interest in the field. For point sources, set <sciencetargetsize> to 0.01. Note that this field is not pre-populated, but the submission checker requires it to be filled.
SPECTRUM / BRIGHTNESS: Following the position and size parameters is a block of science target parameters that are not expected to change from the Phase 1 submission. These include:
INSTRUMENT SETUP: These are from Phase 1, and normally will not change
<aperture> </aperture> GRISM or IMAGE
Additional information is requested for some instrument setups:
GRISM PREIMAGE: If your observation uses the aperture <GRISM>, you will be asked to provide the name of the pre-image field (the <grismpre> field appears after the special requirements). If you will use a GALEX PI team observation for a pre-image, please give the full GALEX team target name. If you will be using a different observation in your own program, use the same name you used for that observation.
A list of PI team and GI planned targets is at http://galexgi.gsfc.nasa.gov/targets/planned/index.html
INTEGRATION TIME: The total time you want to spend in this mode, in seconds. Note that GALEX scheduling is generally by orbit ("eclipse"). Orbits should not be assumed to be longer than 1500 seconds for the purpose of planning observations. Shorter observations can be accommodated, particularly for SNAP observations; longer ones may be rounded to the nearest integral orbit by mission planners.
Note: Spectroscopy proposers should revisit the GALEX Exposure Time Simulator using a pessimism factor of .33 (http://galexgi.gsfc.nasa.gov/tools/ExpTimeCalc.html)
SPECIAL OBSERVATIONAL REQUIREMENTS:
GRAN (Specific GRism ANgle)
FUVONLY: For FUV-only targets, in the parameter <fuvexplain>, please give short explanation of what NUV-bright object(s) (fluxes and field locations) drive the requirement for FUV-only observations.
TIMECRITICAL: For Ephemeris targets, in the parameter <timecriticalexplain>, please give a clear description of the nature and origin of the restrictions on observation times, as well as the resulting time precision required. <timecriticalexplain> The timing of the obeservation during the year does not matter. However, once the first observation has been made, the second needs to be planned for 24 hours later, the third for 48 hours later, and the fourth for 96 hours later. Observations should not be more that 2 hours different from the stated interval.
LOWZODI: If you specifically mentioned low-zodi observations in your proposal,
MOVE (Moving target)
BRIGHTWAIVER: If your field exceeds ANY brightness limit you must enter YES in this tag and the rationale in the <brightwaiverexplain> tag. If you do not require a waiver (i.e. you have checked, and your field is safe, enter NO. Please check your targets against the brightness checker and Zodi background checker at
You can use the GALEX PI team's GMOSAIC tool to explore possible moves of the field center. (http://galexgi.gsfc.nasa.gov/tools/index.html).
Note that that this field is NOT pre-filled, but must have some value entered. Targets that do not pass the brightness checker and do not request and justify a brightness waiver may be dumped from the program by the SODA team.
TIME-TAGGED PHOTONS / COMPRESSION: If you requested time-resolved data
COMMENTS: Use the <comments> field to include other information that the mission planning team will need to schedule and execute your observations correctly. Examples might include coordinating observation with other events, contact information that will change between now and the observations, or data products that you'd like to see but are not now offered (no promises implied).
1. The template is an XML file. You do not need to be familiar with XML to update the template, but a short explanation follows:
3. Please use < to indicate a less-than symbol '<', to avoid confusing the XML parser, or write out the words "less than" in text fields. All other symbols (including '>') are OK.. Please use Å to indicate the Angstrom symbol.
4. The Phase 2 template can be edited with any text editor program.
If you have any questions, please send email to galexhelp@galexgi gsfc.nasa.gov.
Please do NOT contact us individually, as several of us will be on vacation during parts of August.
