Bug ID: 415817
Summary: "Set Coordinates Manually..." always treats input as
J2000 even if Jnow is selected.
Product: kstars
Version: 3.3.9
Platform: macOS Disk Images
OS: macOS
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
The option to "Set Coordinates Manually..." has the option to input RA and Dec
as either J2000 or Jnow. The buttons have no effect, though. The conversion
from J2000 to Jnow is always applied, even if Jnow coordinates were entered and
the Jnow button was clicked. This causes the wrong location to be used if Jnow
coordinates are entered.
STEPS TO REPRODUCE
1. Pointing -> Set Coordinates Manually...
2. In the dialog that pops up, the default is Jnow coordinates. Leave it set
to Jnow and enter Jnow coordinates for Pollux: RA=07h 46m 31.63s,
Dec=27:58:32.82
3. Leave the option set to Jnow and hit "OK".
OBSERVED RESULT
The sky view will change but Pollux will not be in the center. The error is
equal to the difference between Jnow and J2000.
EXPECTED RESULT
The sky view will change and Pollux will be in the center of the view.
The test can be redone by leaving the button set at Jnow but inputting the
J2000 coordinates of Pollux: RA=07h 45m 19.38s, Dec=28:01:34.72. Leave it set
for Jnow and hit "OK". The sky view will now center on Pollux even though the
wrong datum was used.
