isochrone¶
The methods in spexxytools isochrone can be used to manipulate and apply isochrones.
apply¶
With this command one can apply a given isochrone to all stars in a given photometry file. The tool derives effective temperatures, surface gravities and current masses for all entries:
usage: spexxytools isochrone apply [-h] [-o OUTPUT] [--id ID [ID ...]] [--filter1 FILTER1] [--filter2 FILTER2] [--filter1-iso FILTER1_ISO] [--filter2-iso FILTER2_ISO] [--nearest] [--check-teff CHECK_TEFF CHECK_TEFF] [--check-logg CHECK_LOGG CHECK_LOGG] [--check-mact CHECK_MACT CHECK_MACT]
[--quadratic | --cubic]
isochrone photometry
positional arguments:
isochrone File containing the isochrone
photometry File containing the photometry
optional arguments:
-h, --help show this help message and exit
-o OUTPUT, --output OUTPUT
Output file
--id ID [ID ...] IDs from photometry file to copy to the output
--filter1 FILTER1 First filter to use
--filter2 FILTER2 Second filter to use
--filter1-iso FILTER1_ISO
First filter in isochrone to use (--filter1 if empty)
--filter2-iso FILTER2_ISO
Second filter in isochrone to use (--filter2 if empty)
--nearest Use nearest neighbour instead of polynomial
--check-teff CHECK_TEFF CHECK_TEFF
Only apply values if Teff within range
--check-logg CHECK_LOGG CHECK_LOGG
Only apply values if logg within range
--check-mact CHECK_MACT CHECK_MACT
Only apply values if Mact within range
--quadratic Use quadratic polynomial instead of linear one
--cubic Use cubic polynomial instead of linear one
cut¶
Tries to automatically cut an isochrone to given regions (MS, RGB, …):
usage: spexxytools isochrone cut [-h] [-p] input output {MS,SGB,RGB,HB,AGB} [{MS,SGB,RGB,HB,AGB} ...]
positional arguments:
input Input file containing the isochrone
output Output file
{MS,SGB,RGB,HB,AGB} Regions to include
optional arguments:
-h, --help show this help message and exit
-p, --plot Plot result
interpolate¶
Interpolates an isochrone along a given parameter:
usage: spexxytools isochrone interpolate [-h] [--count COUNT] [--column COLUMN] [--space SPACE SPACE] [-p] input output
positional arguments:
input Input file containing the isochrone
output Output file
optional arguments:
-h, --help show this help message and exit
--count COUNT Number of points for new isochrone
--column COLUMN Column used for interpolation
--space SPACE SPACE Space for distance calculations
-p, --plot Plot result
