Calculations to translate coordinates across the sky

Author : David Young

class astrocalc.coords.translate.translate(log, ra, dec, northArcsec, eastArcsec, settings=False)[source][source]

Bases: object

Translate a set of coordinates north and east by distances given in arcsecs

Key Arguments

  • log – logger

  • settings – the settings dictionary. Default False

  • ra – ra (decimal or sexegesimal)

  • dec – dec (decimal or sexegesimal)

  • northArcsec – number of arcsecs to move location to the north

  • eastArcsec – number of arcsecs to move location to the east

Todo

  • replace shift_coordinates class in all other code

Usage

To shift a set of coordinates north and east by given distances:

```python # TRANSLATE COORDINATES ACROSS SKY from astrocalc.coords import translate ra, dec = translate(

log=log, settings=settings, ra=”14.546438”, dec=”-45.34232334”, northArcsec=4560, eastArcsec=+967800

).get() ```

get()[source][source]

translate the coordinates

Return

  • ra – the right-ascension of the translated coordinate

  • dec – the declination of the translated coordinate
