Gaia data, Pan-STARRS photometry, and stream selection masks for the region around the GD-1 stream
Price-Whelan, Adrian M.;
Bonaca, Ana
This file contains:
- relevant columns from Gaia DR2
- Pan-STARRS (PS1) photometry (grizy)
- de-reddened PS1 photometry (g0, r0, etc.)
- binary masks to apply to select out stars that pass our proper motion and color-magnitude diagram selection (pm_mask, gi_cmd_mask)
- a binary mask to apply to select out stars in the stream track defined in Price-Whelan & Bonaca (2018) (stream_track_mask)
- GD-1 positional coordinates (phi1, phi2)
- Proper motions in the GD-1 coordinate system (pm_phi1_cosphi2, pm_phi2)
- Proper motions in the GD-1 coordinate system, corrected for solar reflex motion (pm_phi1_cosphi2_no_reflex, pm_phi2_no_reflex)
To select out probable members of the GD-1 stream in, e.g., Python, use:
from astropy.table import Table
tbl = Table.read('gd1-with-masks.fits')
tbl = tbl[tbl['pm_mask'] & tbl['gi_cmd_mask']]To select out only stars within the stream track identified in Price-Whelan & Bonaca (2018), do:
from astropy.table import Table
tbl = Table.read('gd1-with-masks.fits')
tbl = tbl[tbl['pm_mask'] & tbl['gi_cmd_mask'] & tbl['stream_track_mask']
