Errors

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

Action: Transfer the error 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

'PROX'

X projection

'PROY'

Y projection

'SLIX'

X slice

'SLIY'

Y slice

'BANX'

X band

'BANY'

Y band

CHOICE=' ' is equivalent to 'HIST'.

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.

HIEVARIAB = HIE (ID,I)

Action: Returns the value of the error that has been stored in a given 1-dimensional histogram channel. This corresponds to the square root of the sum of the squares of the weights.

Input parameters:

ID

Histogram identifier.

I

Channel (bin) number.

When HBARX has not been calledHIE returns the square root of the contents of the given channel.

HXEVARIAB = HXE (ID,X)

Action: Analogous to HIE but referring to the channel that contains a given X-value.

Input parameters:

ID

Histogram identifier.

X

X-value.
