Phase II Proposal - Old Format

Target List

A target list must be submitted in ELECTRONIC FORM. The target list must be in plain ASCII text, and the columns MUST BE SEPARATED BY TABS. NO spaces are allowed unless in the comment field (see below) but then mandatorily enclosed within quotes.

Every entry in the target list needs to start with TWO tabs and MUST contain the following information in the order given below:

  1. Blank column

  2. Object Status:
    • A string that is either D (Deferred), H (Hold), or blank (active)
    • The PI should submit the targets as either active or on hold

  3. Program Number:
    • In the form UTYY-N-XXX, where
      YY is the 2-digit year (e.g. 01 for 2001),
      N is the observing period within the year (1-digit integer), and
      XXX is the 3-digit program number assigned by the TAC (e.g. 003; this is given in the message sent to you by the TAC telling you about the fate of your proposal).
    • Examples: UT01-1-001, PSU01-1-014, STA01-1-005

  4. Object Name:
    • Remember to avoid spaces, for NGC 3379 use NGC3379 or NGC_3379
    • For MOS setups, follow with W or E for West or East track

  5. Azimuth Restriction:

  6. Right Ascension:
    • 12:05:36.1 (to 0.1 seconds of time)

  7. Declination:
    • +33:29:08.7 (to arcsecond precision)

  8. Equinox:
    • 2000

  9. V Magnitude:
    • 18.2

  10. Position Angle:
    • Measured in degrees from north through east, including at least one decimal place
    • Use par for parallactic, not zero, as the recommended default PA
    • See the Position Angle Calculator for more detail about PA and AZ restrictions

  11. Priority:
    • Your priority will be that given to you by the TAC
    • You may distribute your objects over the priorities assigned by the TAC, or you may "oversubscribe" your top priority
    • When your higher priority TAC allocation has been depleted, all remaining active targets will be reassigned to lower priority

  12. RA Priority Modifier:
    • This is reserved for a quantitative RA algorithm for highlighting special urgency factors, which a more mechanistic execution of the queue could well overlook. It helps promote delivery of whole data sets and HET partner equity, and helps prevent missed chances for scarce observing opportunity windows.

  13. Setup:
  14. Maximum Seeing:

  15. Sky Brightness:
    • Maximum acceptable sky brightness, expressed as a V-band magnitude
    • Inclusion of real time V-band sky brightness measurements in the night report is under development
    • Do NOT leave blank
    • Consult out HET sky brightness discussion for details

  16. Sky Transparency:
    • Use either P (photometric), S (spectroscopic), or N (not spectroscopic), do NOT leave blank
    • In practice these correspond roughly to P=100-95%, S=95-50% and N=20-50% transmission
    • HET closes under high dust, fire-smoke, or fog conditions
    • Guider flux, DIMM flux, an IR zenithal cloud sensor, weather satellite maps, dust gauges, a scanning wide-angle video camera, and personal gauging are all used continually to monitor the status
    • Exposure times are by and large not scaled for sky transparency, with some allowance possible for significantly opaque yet borderline productive conditions, provided that the scaling in no way vitiates the scientific value
    • Despite any possible scaling, for an accepted observation only the exposure time given by the Phase II plan will be charged

  17. Integration Time:
    • The total shutter open time per visit, in seconds
    • Please keep this number smaller than the track length at the target declination, and a good practice is to limit it to one hour, because of filling factor and scheduling flexibility
    • Occasionally the time may be slightly truncated due to end of track, tight scheduling fits, unforeseen equipment or weather interference, etc; truly shortchanged integrations will not be charged

  18. CRsplit:
    • Number of sub-exposures in which to split the above integration time
    • Subdividing into no longer than 20 min integration splits is important for checking LRS focus and, at least with narrow slits, centering. Splits also allow cosmic ray flagging.
    • CRsplit of 1 means no subdivision, i.e. a single exposure
    • Example: an 1800 exposure time with CRsplit 2 means two 900s exposures

  19. Visits:
    • Number of visits to execute
    • Prescribed integration time and CRsplit will be used for each visit

  20. Done:
    • Initialized to 0
    • The resident astronomers will increment as visits are executed (and decrement for rejections)
    • Because of CRsplits the resulting doneness can be non-integral

  21. Moving Target:
    • A boolean field Y or N whether the target is a moving target
    • Do NOT leave blank
    • Multiple sets of moving targets should use a group ID
    • Each moving target entry should also include a SYN Date
    • If required, a AZ entry can also be specified

  22. SYN Frequency:
    • It specifies the visit cadence in days for synoptic targets
    • Use string RAND#-# for synoptic targets with repeat visits, where the # gives a range on the desirable number of days between visits
    • A minimum frequency of 0 means that you do not mind having the target observed in both East and West tracks.
    • RAND1-7 means that the target repeat visits should occur at a spacing of between 1 and 7 days; be aware that with high priority and good observing conditions this can produce nearly all 1 day spacing
    • Leave blank for non-synoptic targets

  23. SYN Dates:
    • For synoptic targets with visits required on or after specific UT dates
    • Format for dates should be sYYYYMMDD in UT dates, where s is either a   =   for only on this date, or a   >   for after or on this date, or a   <   for before or on this date.
    • Multiple specific dates should be separated by a comma with no space e.g. =20040412,=20040415. If your targets have e.g. different exposure times or azimuth restrictions on different dates, then you will need to create formally separate target indentities for each case
    • Date ranges may be given by using two different formats: >20040412,<20040420 or >20040412-20040420.
    • Leave blank for non-synoptic targets
    • Please note that with these systems the synoptic targets will be on hold until their due date comes due and then will be again on hold after they expire

  24. Group ID:
    • For programs that require visits to multiple targets
    • For all targets in a group give them a unique identifier, e.g. mygroup1
    • Leave blank for ungrouped observations

  25. Standard CALS:
    • A boolean string Y or N indicates whether the standard calibration set is necessary
    • Calibration Information explains the standard and some available nonstandard (special) calibrations
    • Special calibrations must be listed in the Phase II submission form, and may be charged to the PI if they take time away from science within the night

  26. Flux standard:
    • Give the required quality class of flux standard in terms of the HET scale from 1 to 4 (viz. standards list)
    • OR enter N meaning none is required

  27. Radial Velocity standard:
    • Give the required quality class of RV standard in terms of the HET scale from 1 to 4 (viz. standards list)
    • OR enter N meaning none is required

  28. Telluric standard:
    • Give Y or N depending on whether a telluric standard is required (viz. standards list )

  29. Skyflat:

    • If there are spaces, enclose in double quotes.
    • Keep it as brief as possible, starting with anything vital to know about at the time of execution, e.g. any request ("Take adjacent ThAr") or ID clarification ("Fainter star of close pair") or intention that might be misread from a finding chart ("Transect BOTH nuclei with the slit").
    • For blind offset setups, give the name of the .xy setup file.
    • For MOS setups, give the name of the .cfg setup file.
    • For MOS setups, also specify whether this is the West or East track.
    • Users tend to confuse the intentions of the COMMENT and the Phase II printed notes. COMMENT is for the most concise, vital, real-time instructions necessary for the visit; not the lengthy tome that goes in the Phase II printed notes.
    • Format Examples:
      COMMENT  "Take adjacent ThAr"
      COMMENT  template_exposure

    We have created a few examples with different formats to aid you in creating your own Phase II target list.
