# HR-DTG Project
**This is the note to manage our project.
We continue to share files, plots and have discusssions on slack :upside_down_face:**
* Zhen Yuan (ZY)
* Tadafumi Matsuno (TM)
* Erika Holmbeck (EH)
* Tatyana (TS)
* Linda Lombardo (LL)
* Federic Sestito (FS)
* Projjwal Banerjee (PB)

## :radioactive_sign: Very Important Things
**The agreed format of abundance table. Keep separate lines for EW and Syn methods**

**

* 		ID (from spreadsheet)
* 		Species (no space; e.g., “FeI”)
* 		Wavelength ({:.2f} format)
* 		EP ({:.2f} format)
* 		loggf ({:.2f} format)
* 		EW (mA; {:.1f})
* 		method (“ew” or “syn”)
* 		HFS_flag (“True” or “False” flag)
* 		limit_flag (“True” or “False”; upper limit indicator)
* 		loge (abundance)





## :book: Shared Files

- DTG tables
https://docs.google.com/spreadsheets/d/13p4KGN7F93MIXR7y7jwt3rb-N-L-6g1dDuZABt9Oy_U/edit#gid=0


## :calendar: Task

- July (first meeting on July 12th)
    - All the P1 stars analyzed [name=TS, EH, TM]
    - NEMP star analyzed [name=LL]
    - Starting Writing P1 paper [name=ZY]
    - Starting Writing NEMP paper [name=LL]


##  :pencil: Meeting Notes

June 1st
- P1
    - Comparisons between analaysis of 5 analyzed P1 stars [name=TS,EH,TM]
    - Remove Mg triplet for cool giants (basically when it’s saturated), but we might need to include it for certain stars. Avoid it if you have other Mg lines to use.
            - Remove the Ba II line at 4934
            - Remove Ca I at 4226(?) in most cases (follow similar rules as for Mg)
            - Remove Sr II at 4161 if it’s too weak
            - [name=ZY] will check if loggf and EP are the same for each line.
    - 8-2 new P1 stars will be shared [name=TS,EH,TM]


- NEMP [name=LL]    
    - Could Linda put the results on slack?
- GaiaDR3
    - improvement on stellar parameters after DR3 (maybe not much on Teff, logg) [name=FS]
    - Stars with high Teff need to be checked with 3D extinction map [name=FS]. 
    - P1 parameters are good.
