NAME

mHdrWWTExec - None

SYNOPSIS

mHdrWWTExec [-d level] tileLevel hdrDir

DESCRIPTION

Runs mHdrWWT to create all the header template file needed for WWT TOAST tiles down to a specified level.

OPTIONS

-d level

Turns on debugging to the specified level

ARGUMENTS

tileLevel

The depth to which the tiles are created. Level 0 is just produces the all-sky header, 1 is that plus the four main quadrants, etc.. Level 4 produces files like "tile3102.hdr".

hdrDir

Output directory for the header files.

RESULT

The set of header files.

MESSAGES

OK

[struct stat="OK", level=n, nheader=nheader]

ERROR

Problem creating output header directory.

ERROR

Problem with output header directory.

ERROR

[hdrDir] is not a directory.

ERROR

mHdrWWT error message

EXAMPLES

$ mHdrWWTExec 4 hdrs

[struct stat="OK", level=4, nheader=341]

BUGS

The drizzle algorithm has been implemented but has not been tested in this release.

If a header template contains carriage returns (i.e., created/modified on a Windows machine), the cfitsio library will be unable to read it properly, resulting in the error: [struct stat="ERROR", status=207, msg="illegal character in keyword"]

It is best for the background correction algorithms if the area described in the header template completely encloses all of the input images in their entirety. If parts of input images are "chopped off" by the header template, the background correction will be affected. We recommend you use an expanded header for the reprojection and background modeling steps, returning to the originally desired header size for the final coaddition. The default background matching assumes that there are no non-linear background variations in the individual images (and therefore in the overlap differences). If there is any uncertainty in this regard, it is safer to turn on the "level only" background matching (the "-l" flag in mBgModel.
