pydl.pydlutils.sdss.sdss_astrombad(run, camcol, field, photolog_version='dr10')

For a list of RUN, CAMCOL, FIELD, return whether each field has bad astrometry.

Parameters:

run, camcol, fieldint or array of int

Run, camcol and field. If arrays are passed, all must have the same length.

photolog_versionstr, optional

Use this version of photolog to obtain the obBadfields.par file, if PHOTOLOG_DIR is not set.

Returns:

numpy.ndarray of bool

Array of bool. True indicates the field is bad.

Raises:

ValueError

If the sizes of the arrays don’t match or if the array values are out of bounds.

Notes

Reads data from $PHOTOLOG_DIR/opfiles/opBadFields.par.

If there is a problem with one camcol, we assume a problem with all camcols.
