QUERY EXOPLANET DATA

SELECT A PAIR OF EXOPLANET/PARENT STARS PARAMETERS TO PLOT

SELECT THE DESIRED SPECTRAL TYPE OF EXOPLANET PARENT STARS YOU WISH TO QUERY (THE SUN IS TYPE 'G')





SELECT THE PAIR OF PARAMETERS YOU WISH TO PLOT ON THE GRAPH





DO YOU WISH USE A LOGARITHMIC SCALE FOR THE HORIZONTAL 'X' AXIS (FIRST FIELD SELECTED)
NO

YES

DO YOU WISH USE A LOGARITHMIC SCALE FOR THE VERTICAL 'Y' AXIS (SECOND FIELD SELECTED)
NO

YES


OPTIONAL ENTRY OF SEARCH STRING. ONLY PARENT STAR SYSTEM NAMES WITH A CASE INSENSITIVE MATCH WILL BE RETURNED, UNLESS THE WILDCARD CHARACTER "*" IS INCLUDED.



DO YOU WISH TO GUARANTEE THE INCLUSION OUR SOLAR (SUN) SYSTEM IN THE SEARCH STRING PLOT?
THE PLOT POINTS FOR THE SOLAR SYSTEM WILL BE WHITE TO DISTINGUISH THEM FROM THE SUBJECT PLOTS, EVEN THOUGH OUR SUN IS YELLOW TYPE 'G2.2'.
THE SOLAR (SUN) PLOT WILL INCLUDE PLUTO.
NO

YES



OPTIONAL ENTRY OF PARAMETERS TO ONLY RETURN EXOPLANETS WITHIN DEFINED LIMITS OF (A) GIVEN PARAMETER(S).
USEFUL FOR FINDING EXOPLANETS OF EARTH LIKE MASS OR RADIUS IN THE HABITABLE ZONE.

JUST ONE PAIR OF DEFINING LIMITS CAN BE SUBMITTED, BUT MORE TO IF SO DESIRED.

NO PAIR OF LIMITS CAN HAVE EQUAL VALUES. EG, UPPER AND LOWER BOLOMETRIC HABITABILITY FACTOR LIMITS CANNOT BOTH BE EQUAL TO 1.5.
IF ANY PARAMETER, OTHER THAN DECLINATION, STELLAR METALLICITY OR ABSOLUTE BOLOMETRIC MAGNITUDE IS INADVERTENTLY ENTERED AS A NEGATIVE NUMBER, IT WILL BE CONVERTED TO ITS (POSITIVE) ABSOLUTE VALUE. EG, -1.3 BECOMES 1.3.
IF AN UPPER LIMIT IS INADVERTENTLY ENTERED WITH A LESSER VALUE THAN ITS CORRESPONDING LOWER LIMIT, THEN THE VALUES WILL BE SWITCHED.
ANY NON-NUMERICAL ENTRY OR EMPTY FIELD WILL DEFAULT TO ZERO, AND IF NO VALID PAIR(S) OF DEFINING LIMITS ARE SUBMITTED, THEN THIS OPTION WILL BE IGNORED IN THE QUERY.

SELECT THE 'AND' OPTION IF YOU WISH TO QUERY EXOPLANET(S) SATISFYING BOTH THE MASS AND RADIUS CONDITIONS.
OTHERWISE, SELECT THE 'OR' OPTION IF YOU YOU WISH TO QUERY EXOPLANETS SATISFYING EITHER CONDITION.
NOTE: THIS OPTION ONLY BECOMES RELEVANT IF THE DEFINING LIMITS OF THE EXOPLANET RADIUS AND MASS ARE SUBMITTED.
