usage code
- @review: when complete, clean unit_conversion class - @review: when complete add logging - @review: when complete, decide whether to abstract class to another module
Methods
dec_decimal_to_sexegesimal
(dec[, delimiter])Convert a declination between decimal degrees and sexegesimal.
Convert a declination from sexegesimal format to decimal degrees.
get
()get the unit_conversion object
ra_dec_to_cartesian
(ra, dec)Convert an RA, DEC coordinate set to x, y, z cartesian coordinates
ra_decimal_to_sexegesimal
(ra[, delimiter])Convert a right-ascension between decimal degrees and sexegesimal.
Convert a right-ascension from sexegesimal format to decimal degrees.
-
dec_decimal_to_sexegesimal
(dec, delimiter=':')[source] ∞ Convert a declination between decimal degrees and sexegesimal.
Precision should be respected.
Key Arguments
dec
– DEC in decimal degrees. Will try and convert to float before performing calculation.delimiter
– how to delimit the RA units. Default :
Return
sexegesimal
– ra in sexegesimal units
Usage
Todo
replace dec_to_sex in dryxPython in all code
from astrocalc.coords import unit_conversion converter = unit_conversion( log=log ) dec = converter.dec_decimal_to_sexegesimal( dec="-3.454676456", delimiter=":" ) print(dec) # OUT: -03:27:16.8
-
dec_sexegesimal_to_decimal
(dec)[source] ∞ Convert a declination from sexegesimal format to decimal degrees.
Precision should be respected. If a float is passed to this method, the same float will be returned (useful if unclear which format coordinates are in).
The code will attempt to read the sexegesimal value in whatever form it is passed. Any of the following should be handled correctly:
+1:58:05.45341
01:5:05
+1 58 05.45341
-23h53m05s
Key Arguments
dec
- DEC in sexegesimal format.
Return
decDeg
– declination converted to decimal degrees
Usage
Todo
replace dryxPython declination_sexegesimal_to_decimal with this version in all my code
replace coords_sex_to_dec in all code
from astrocalc.coords import unit_conversion converter = unit_conversion( log=log ) dec = converter.dec_sexegesimal_to_decimal( dec="-23:45:21.23232" ) print(dec) # OUTPUT: -23.7558978667
-
get
()[source] ∞ get the unit_conversion object
Return

- @review: when complete, clean get method - @review: when complete add logging
-
ra_dec_to_cartesian
(ra, dec)[source] ∞ Convert an RA, DEC coordinate set to x, y, z cartesian coordinates
Key Arguments
ra
– right ascension in sexegesimal or decimal degress.dec
– declination in sexegesimal or decimal degress.
Return
cartesians
– tuple of (x, y, z) coordinates
Todo
replace calculate_cartesians in all code
Usage
from astrocalc.coords import unit_conversion converter = unit_conversion( log=log ) x, y, z = converter.ra_dec_to_cartesian( ra="23 45 21.23232", dec="+01:58:5.45341" ) print(x, y, z) # OUTPUT: 0.9973699780687104, -0.06382462462791459, 0.034344492110465606
