static int | uves_correct_badpix (cpl_image *master_bias, uves_propertylist *header, int **badmap, bool mark_bad) |
Correct bad pixels. | |
int | uves_correct_badpix_all (cpl_image *master_bias, uves_propertylist *mbias_header, enum uves_chip chip, int binx, int biny, int mark_bad, bool red_ccd_new) |
Correct all bad pixels on a chip. | |
void | uves_badmap_free (int ***badmap) |
Deallocate bpm position. | |
static int ** | dup_map (int badmap[][4]) |
Copy bpm to heap. | |
int ** | uves_get_badpix (enum uves_chip chip, int binx, int biny, int mark_bad, bool red_ccd_new) |
Get hard-coded bpm map. |
Correct the bad pixels in an image
static int uves_correct_badpix | ( | cpl_image * | master_bias, | |
uves_propertylist * | header, | |||
int ** | badmap, | |||
bool | mark_bad | |||
) | [static] |
Correct bad pixels.
master_bias | The image to correct | |
header | Image FITS header, | |
badmap | Matrix of bad pixel traps. Each row is in the format (xstart, ystart, xend, yend), except the last row which must be (-1, -1, -1, -1). | |
mark_bad | If true, the relevant pixels are not interpolated but simply marked as bad. |
The bad pixels are replaced by the average of nearest good pixels in the same column.

mark_bad | If true, the relevant pixels are not interpolated but simply marked as bad. |
The bad pixels are replaced by the average of nearest good pixels in the same column, or simply marked as bad.
The positions of bad pixels are hard-coded (as function of UVES chip).
