Missing parameters of SkyCoord object
Summary
The SkyCoord
object which is used to perform coordinate transformation
between e.g. RA/Dec and Alt/Az coordinates requires additional parameters
in order to properly apply light refraction in the atmosphere.
This parameters are:
-
obswl
(observed wavelength), default value should be set to0.35\mu
, -
relative_humidity
, default value should be set to0.5
-
temperature
, default value should be set to10\degree C
-
pressure
, default value should be set to790hPa
Further investigation would require a scan of different combinations of the above parameters.
Steps to reproduce
Create a SkyCoord
object and run the default transformation providing only the telescope geodetic coordinates.
Observe that refraction is not accounted for.
What is the expected correct behavior?
Atmosphere refraction should be correctly applied
