The built-in star data I am using are currently being populated from in-the-sky.org so it is possible it has a different proper motion speed than what you are looking at
If you don't have the proper motion speed and proper motion angle, do you have the proper motion along the Right Ascension and Declination? in-the-sky.org uses a proper motion speed and proper motion angle (example: Pollux) but some places like Wikipedia use proper motion along the RA and declination (example: Pollux)
Out of curiosity, which star/data are you looking at? If you have details I might be able to add functionality to account for your data in the next release
from star-chart-spherical-projection.
I am using hipparcos catalogue where . There are pmRA and pmDEC values. Can I pass pmSpeed and pmAngle from pmRA and pmDEC? Or do i download new catalogue in-the-sky.org. I can't this.
from star-chart-spherical-projection.
The current behavior of this package uses about a hundred handpicked built-in stars where I've taken their data from in-the-sky.org The stars aren't web scrapped or downloaded, they are part of the backend and are distributed as part of the package so you shouldn't need to do anything on your end to uses these built-in stars.
The backend uses this CSV file for the built-in 100+ stars
If you want to add a star that isn't currently in the built-in star list, you can use the newStar()
function. When you add a newStar()
, you have the option to make the new star with either the PM speed/angle or the PM Declination/RA and it will be incorporated into the rest of the plotting like any the built-in stars
Do you have a link for the Hipparcos catalogue star you want to add or an example of what you are trying to do? I might be able to answer your question or add some new functionality to incorporate it
from star-chart-spherical-projection.
I will add stars where hiparcos catalogue after limiting magnitude as 5. I got catalogue from hipparcos catalogue. There are pmRA, pmDEC values and HIPS ID of stars.
from star-chart-spherical-projection.
To add a new star with the PM RA/DEC values, you want to use the newStar function that uses PM RA/Declination and then set the HIP as the star name
import star_chart_spherical_projection as scsp
hip_star = scsp.newStar(starName="<HIP>",
ra="<RA Hours Information Here>",
dec=<Declination Information Here>,
properMotionSpeedRA=<PM RA>,
properMotionSpeedDec=<PM Dec>,
magnitudeVisual=<Magnitude>)
scsp.plotStereographicProjection(northOrSouth="North",
userDefinedStars=[hip_star])
from star-chart-spherical-projection.
