Observing Extended Objects (ie. Nebulae) with IGRINS

Proposals

• McDonald Observatory Proposals

Exposure Time Estimation

• Update when KHU website comes back online

• A0V star Signal-to-Noise Estimates

Observing Procedures

• https://github.com/kfkaplan/igrins_observability

• The McDonald Control Room and 107' Telescope

• Beginning of night

  • TCS Startup

  • Starting up IGRINS computers & data taking software

  • Taking Calibrations

  • Old Dome Opening Procedure

  • Check telescope pointing

    • Telescope Pointing Procedure

    • How to zero the telescope pointing in TCS

  • Focus telescope

• Rotating the instrument

  • Position Angle Changes

  • Old Rotation PA -> Encoder Table for IGRINS

  • Or get encoder number and finder chart from observability.py

• Find your target

  • Make finder charts: https://github.com/kfkaplan/igrins_observability

  • Slit Viewer Field-of-View

  • Dither Directions in the Slitview Image

  • Autoguiding

• Taking your data

  • Using the IGRINS Data Taking Package

• End Of Night Procedure

• End of Run Shutdown

• Data Requests and Transfers
  
  

Cosmic Ray Removal

• Download lacosmic python version and IGRINS script, put in indata directory, modify script variables, run for a night.  Need to upload code somewhere.

Data Reduction

• NOTE: I (Kyle) use a modified version of plp-testing to output 2D variance maps.  Email me if you are interested in that feature.  Needed for error propagation in 2D.

• https://github.com/leejjoon/plp/tree/testing

• IGRINS Pipeline Wiki

• How to run pipeline

Data Analysis

• https://github.com/kfkaplan/plotspec - (public version of) the main code for nearly all my 2D IGRINS data analysis

Pointings, maps, and datacubes

• https://github.com/kfkaplan/igrins_observability

• Describe basic procedure here, maybe upload example code later

Carefully check all lines in line list for contamination

• Describe procedure here.  This is a time consuming process, may later write code to semi-automate procedure

• In cases of poor wavelength calibration, add velocity correction to any lines not centered at v = 0 km/s
