r.covar / r.in.hdf

[Stephan Eickschen]

Hi,
I have questions regarding to programs:

r.covar:
	Do I understand it right, that using the -m flag will include
	zero values from the datasets in the computation but the mask
	is still valid (zero in the area of interest will be taken into
	account ,but everything	"not visible" / masked not) ?

r.in.hdf:
	I want to import HDF datasets from CDROM, distributed by the
	NSIDC (National Snow and Ice Data Center
	http://www-nsidc.colorado.edu/) with datasets in a polar-
	stereographic projections. The datasets are centered on the
	poles and cover regions up to 
	g.region reports:

		CURRENT REGION: N=60S  S=80S  RES=0:06  ROWS=200
                E=45E  W=45W  RES=0:20  COLS=270
		PROJECTION: 3 (Latitude-Longitude)
		ZONE:       0

	r.in.hdf reports:

Reading HDF file "/hosts/body/CDROM/s3b/1997/apr/970401.19h"
rows = 332, cols = 316
Writing GRASS output file: hdf.rast01
WARNING: G_set_window(): Illegal latitude for North

	Does anybody have a suggestion what is going on here?

Sincerly and thanks in advance for any reply,

	Stephan
