Description

12/17/24 Update: I was made aware that the MRT files had the J-band and H-band column header labels incorrectly switched (this occured when converting the CSV files to MRT). I have fixed this mistake in this version. The CSV files were correct the entire time. No data have been changed. Apologies for any inconvinence this may have caused. 

 

Data for Resolved Near-infrared Stellar Photometry from the Magellan Telescope for 13 Nearby Galaxies: JAGB Method Distances

The files are provided in two formats. A CSV format with a single line header, and a MRT files (zipped) written in the machine-readable format used by AAS & CDS: https://journals.aas.org/mrt-overview/

Column descriptions in photometry catalogs:

X/Y: Image coordinates from Fourstar camera

J, J_err: J-band magnitudes and photometric errors returned from DAOPHOT/ALLFRAME

H, H_er: H-band magnitudes and photometric errors returned from DAOPHOT/ALLFRAME

K, K_err: K-band magnitudes and photometric errors returned from DAOPHOT/ALLFRAME

chi: chi value returned from DAOPHOT/ALLFRAME

sharp: sharpness value returned from DAOPHOT/ALLFRAME

ra/dec: RA/Decl 

RGC: semi-major axis distance

 

Notes on versions: all catalogs from all versions contain the same information, style was just adjusted to adhere to AAS standards. 

 

Methods

A set of python scripts originally published on GitHub are available in version "fourstar" of this Zenodo deposit: doi: 10.5281/zenodo.10606945.

  • 9/18/24 NOTE: I have been made aware there are some issues with the MRTs that I think were created when they were being transferred from CSV to MRT files. I am working on fixing these, but the CSV files are still correct and can be used.
