streamdf.calc_stream_lb(vo=None, ro=None, R0=None, Zsun=None, vsun=None)[source]

Convert the stream track to observational coordinates and store

Deprecated since version 1.12: Use streamTrack() and the resulting track.ll(tp), track.bb(tp), track.dist(tp), track.vlos(tp), track.pmll(tp), track.pmbb(tp) accessors, or track.cov(tp, basis="galsky") for sky-coordinate covariances. Will be removed in v1.14.

Parameters:

  • ro (float or Quantity, optional) – Distance scale for translation into internal units (object-wide default.

  • vo (float or Quantity, optional) – Velocity scale for translation into internal units (object-wide default.

  • R0 (float or Quantity, optional) – Distance to the Galactic center (object-wide default.

  • Zsun (float or Quantity, optional) – Distance to the Galactic plane (object-wide default.
