KiraGetRS[{sec1, {gli1, ...}}]
returns the number of
positive and negative propagator powers ( and in
the Kira/Reduze syntax) for the GLI
integrals belonging to
sector sec1
. The input can be also a list of such
entries.
If the option Max
is set to True
(default),
only the largest {r,s}
combination made of the largest
r
and the largest s
values in this sector will
be returned. Otherwise, the function will return the
{r,s}
-pair for each GLI
.
KiraGetRS
can directly handle the output of
FCLoopFindSectors
. Furthermore, the function can also deal
with a simple list of GLI
s as in
KiraGetRS[{gli1,gli2,...}]
.
If the option Top
is set to True
, and the
input is a list of the form
{{sec1, {gli11, ...}}, {sec2, {gli21, ...}}, ...}
then the
output will consists of a list of top sectors and the largest possible
{r,s}
combination.
