The attached figures show several examples of the comparison between the standard AAR product (crosses) and the non-deglitched AAR (asterisks).

Table 1 displays the results of the line flux calculation after a Gaussian fit, for all those lines in the three observations in which points flagged as glitched were found.

Table 1: Comparison between different processing methods

Source	Line	Line flux	Line flux	%
	( m)	standard AAR	non-deglitched AAR	discrepancy
		(W cm )	(W cm )
1	24.31	4.70	5.31	11.5
	25.88	7.79	8.78	11.3
2	15.55	4.81	6.11	21.3
3	10.51	3.01	5.48	45.1
	15.55	3.88	1.10	64.7
	25.88	3.38	4.77	29.1

 

The results of the analysis are:

1.

Most spectral lines are not affected by glitch  removal.

2.

In few lines, some points at the wings of the line are flagged as glitched, causing the line profile in this region to deviate from the non-deglitched one.

3.

In few lines, many points belonging to the line are flagged as glitched. Glitch removal applied to these points introduces a substantial error in the line profile and in the line flux.

4.

For those cases described above, the non-deglitched line profiles can be fitted by a Gaussian function much better than the deglitched ones.
