Add New Stars and Save Output to CSV

Add a New Star to Existing Data with newStar Class

• Users can now add new stars (fix to Issue 1)
• Two methods to add new stars to a plotStereographicProjection() and finalPositionOfStars()

1. newStar(starName=None, ra=None, dec=None, properMotionSpeed=None, properMotionAngle=None, magnitudeVisual=None)

• A new star with a proper motion speed and a proper motion angle

3. newStar(starName=None, ra=None, dec=None, properMotionSpeedRA=None, properMotionSpeedDec=None, magnitudeVisual=None)

• A new star with the proper motion speed for right ascension and declination

userListOfStars -> builtInStars

• Renamed argument userListOfStars to builtInStars

New argument to plotStereographicProjection()

• userDefinedStars: List of newStar objects of stars the user has added
• onlyDisplayUserStars: Only display the stars defined by the users (userDefinedStars)

New argument to finalPositionOfStars()

• userDefinedStars: List of newStar objects of stars the user has added
• onlyDisplayUserStars: Only display the stars defined by the users (userDefinedStars)
• save_to_csv: CSV filename and location to save final star positions with headers ["Star Name", "Right Ascension (HH.MM.SS)", "Declination (DD.SS)"]

New Built-In Star

• Thuban with updated star_data.csv

Bug fixes and README.md edits
New pytest for additional arguments: 141 tests

Pytests: 82 tests

82 error handling pytests for:

• finalPositionOfStars()
• plotSterographicProjection()

finalPositionOfStars() and README edits

• Release for new function: finalPositionOfStars() returns a dictionary of the position of stars
• Update to README for edits

maxMagnitudeFilter optional flag

Set up maxMagnitudeFilter optional flag and adds additional stars (total = 107)

Bug fix for displaying Year

Bug fix: BCE = -2000 years ago

if yearSince2000 >= -2000: year_bce_ce = "{0} C.E".format(yearSince2000 + 2000) # postive years for C.E
if yearSince2000 < -2000: year_bce_ce = "{0} B.C.E".format(abs(yearSince2000 + 2000)) # negative years for B.C.E

showPlot() optional argument

New optional argument for generating charts "showPlot" (defaults to True) that triggers plt.show(). Can turn off showing plot, useful for running multiple charts at once

plotStereographicProjection(userListOfStars=[],
northOrSouth=None,
declination_min=None,
yearSince2000=0,
displayStarNamesLabels=True,
displayDeclinationNumbers=True,
incrementBy=10,
isPrecessionIncluded=True,
showPlot=True,
fig_plot_title=None,
fig_plot_color="C0",
figsize_n=12,
figsize_dpi=100,
save_plot_name=None)

userListOfStars with error handling

userListOfStars with error calls for current stars

v1.1.2 Minor edits

Minor edits to README

Beta release: Precession of the equinoxes

New flag for including precession for long-scale star charts, defaults to True (isPrecessionIncluded)

Stable release: function rename

plotStarChart() --> plotStereographicProjection() for clarity of type
