Description
Section 5.1 for the SDRS has the psGetSidereal() function accept floating point
Modified Julian Days (MJD). Should this be an integer or is it expressed in
terms of fractional days? Is this function to calculate the Sidereal days
automatically or only provide a conversion from MJD to Sidereal days based on
the input of MJD? If automatic,what's the purpose of inputting MJD?
What are the units on longitude, radians or degrees? If degrees, is the range 0
to 360 or -180 to 180? How are east and west oriented with is measurement?
Libtai doesn't have a Sidereal conversion. How should this be done? Can you
provide an algorrithm?

psTime functions have changed significantly in SDRS-06, hence this bug is no
longer relevant.
Note:
See TracTickets
for help on using tickets.
Maybe this function should be renamed to psTimeToSidereal(psTime time, float
longitude) and the first argument changed to the psTime standard?
