Description of the parameter table of the SLIPCAT

Start	The first time detected.
End	The last time detected.
PA	Position angle of the centroid at the first time, counterclockwise from north pole.
HGLon	Longitude of the centroid at the first time in heliographic coordinate. Derived from the heliographic position of spacecraft and the position angle of the prominence.
HGLat	Latitude of the centroid at the first time in heliographic coordinate.
P/M	P: How many seperate parts in the prominence; M (Y or N): Is the part a major one compared to other parts.
Frames	Number of frames in which the prominence is detected.
CL	Confidence level. Number 1 has the highest liklihood to be a prominence.
r_cen	Heliocentric distance of the brightness centroid of the prominence.
PA_cen	Position angle of the brightness centroid of the prominence.
r_top	Heliocentric distance of the top of the prominence.
Area	Projected area of the prominence on the plane of the sky.
Length	Characteristic length of the prominence (i.e., the length of the spine of the prominence).
Brightness	Average brightness (i.e., digital number, DN) of the prominence.
Mean	Mean value of the given parameter during the detection.
Min	Minimum value of the given parameter during the detection.
Max	Maximum value of the given parameter during the detection.
v	Average first time derivative of the given parameter (i.e., the slope of the linear fitting line of the given parameter during the detection).
a	Average second time derivative of the given parameter.
n	Clickable cell and highlight the multiple-part prominence.
2	Highlight the prominence with CL=2.
3	Highlight the prominence with CL=3.
