CALL HUNPAK (ID,CONTEN*,CHOICE,NUM)

Action: Transfer the contents of a histogram or a selected projection of a 2-dimensional histogram into the local array.

Input parameters:

ID

Histogram identifier

CHOICE

Character variable selecting subhistograms (irrelevant for the 1-dimensional case)

'HIST'

the 2-dimensional histogram itself. Default CHOICE=' ' is equivalent to 'HIST'.

'PROX'

X projection

'PROY'

Y projection

'SLIX'

X slice

'SLIY'

Y slice

'BANX'

X band

'BANY'

Y band

NUM

Serial order of the slice or band that is requested. If NUM=0, it is assumed to be 1.

Output Parameter:

CONTEN

Array to be dimensioned at least to the number of channels of the histogram (or projection), i.e. DIMENSION CONTEN(NX) in the 1-dimensional case and DIMENSION CONTEN(NX,NY) in the 2-dimensional case.

HIVARIAB = HI (ID,I)HIJVARIAB = HIJ (ID,I,J)

Action: These functions return the channel contents in a given histogram bin in the 1-dimensional and 2-dimensional case respectively.

Input parameters:

ID

Histogram identifier

I

Bin number in X-dimension.

J

Bin number in Y-dimension (2-dimensional case, i.e. HIJ only)

• When I, J are zero, then HI/HIJ returns the number of underflows
• When NX, NY are respectively the number of channels in X and Y and I=NX+1, J=NY+1, then HI/HIJ returns the number of overflows

HXVARIAB = HX (ID,X)HXYVARIAB = HXY (ID,X,Y)

Action: These functions return the channel contents in a given histogram of the bin which contains a given value in X (1-dimensional case) or a given pair of (X,Y) (2-dimensional case).

Input parameters:

ID

Histogram identifier

X

X-value

Y

Y-value (2-dimensional case, i.e. HXY only)
