  • Finder charts (we recommend using Kyle Kaplan's python based tool)
  • A worklist with your targets to be uploaded into TCS (See page on worklists )
  • Rotator settings (link to rotator guidelines)

  • Finder charts (see IGRINS Observing Planner).

  • Encoder settings for PA’s if you plan to rotate IGRINS (see Rotation PA -> Encoder Table for IGRINS).

  • Offset box positions for offset guide stars (

    if needed - use Kyle's tool)

    found using IGRINS Observing Planner).

  • Offsets to nearby bright stars to check telescope pointing in faint or crowded fields (need to add to Kyle's code the option to give a small list of offset stars)

  • A list of nearby A0V standard stars: You can use either our A0V star TCS worklists (already uploaded to TCS for observers to use) or the IRTF Locator for Nearby A0V and G2V Stars:

     choose

     choose either MMT (31ºN,

    110ºW

    110ºW)  or APO

    (32ºN, 105ºW)

    (32ºN, 105ºW).

  • A list of targets to observe with priority and exposure times calculated for your required SNR (see SNR Estimates and Guidelines at McDonald).

  • Airmass Charts for all targets to help plan observations. We recommend using STARALT (keep in mind this tool does not account for daylight savings time--during daylight savings all airmasses will occur 1 hour later than the appear on the chart).

  • A book, a show, or work to do if the weather is bad.

  • Snack(s) of choice (the astronomer lodge feeds us well, but it can be nice to have a special snack during observing!)

  • Caffeine (if not a coffee or tea drinker)! The astronomer lodge provides coffee and tea and the observing room has a coffee maker and kettle.
