ePESSTO+ Year 1+2 - Final SOFI Imaging reduction

Summary:

Data processing for the ePESSTO+ DR1 resulted in 556 reduced SOFI images of which 232 are observed in J-band, 228 are observed in H-band, and 96 are observed in Ks-band. Detailed notes on the data reduction are found below.

2019-05-13:

The AT2019ahk J and H-band images are affected by prominent instrumental noise in the lower right quadrant of the detector; however, as the data was obtained with separate sky frames via beam switching, the transient location is not extremely affected.

2019-07-30:

The SN2017hhl J and H-band reductions with the pipeline result into images

name_20190730_H_merge_59669_1.fits

name_20190730_J_merge_59669_1.fits

due to no object name added in the used OB.

The SN2017hhl J and H-band reduced images had also some sky subtraction residuals in the default PESSTO pipeline reduction. The images were re-reduced without the illumination correction step, which appeared to improve the image quality.

2019-07-30:

The SN2018bsz Ks-band observations are split by the PESSTO pipeline by default into two reduced images:

SN2018bsz_20190730_Ks_merge_59669_2.fits

2019-08-20:

The SN2019mry J-band observations have major quality issues with the final 4 images of a sequence of 9 exposures; the following frames were excluded from the final reduction:

2019-08-22:

The SN2019ltw J-band observations cover two sequences of observations. Both are reduced by the pipeline resulting in

SN2019ltw_20190822_J_merge_59669_2.fits

However, the first reduced image is very poor in quality, resulting from raw frames obtained in the beginning of the night with a high sky background level.

2019-11-06:

The AT2019udc J-band sequence of 4 images has prominent detector noise in the following frame, which was excluded from the reductions:

2019-11-06:

The GRB190829A J-band observations were obtained with a dither pattern that is not that of standard programme template OBs. To enable PESSTO pipeline reduction, and to exclude raw frames that have notable noise, only the following 12 frames from a sequence of 24 exposures were used:

2019-12-18:

The SN2019esa H-band sequence of ON-OFF images is obtained with an unusual ON-OFF order, has a non-equal number of ON (6) and OFF (4) exposures, and has a possibly tracking related issue in the ON frames that results in a 'double image' if 4+4 frames are used; the reduction was carried out after excluding the following frames:

The SN2021hwk H-band reduced image had also some sky subtraction residuals in the default PESSTO pipeline reduction. The image was re-reduced without the illumination correction step, which appeared to improve the image quality.

The SN2021jap J-band observations are heavily affected by prominent instrumental noise in the upper right quadrant of the detector; the data was reduced without the following first image of a sequence of 4 exposures with the target located in that quadrant:

The AM0702-601N H-band reduced image had also some sky subtraction residuals in the default PESSTO pipeline reduction. The image was re-reduced without the illumination correction step, which appeared to improve the image quality.

The SN2018hle JH-band sequence is very poor in quality. It is not obvious how to improve the J-band processing and the resulting final reduction is based on the full observing sequence. However, the H-band reduction was carried out based on only the following last 4 images of the sequence of 12 exposures:

Astrometry

For the following 71 reduced images the PESSTOSOFIPHOT task of the PESSTO pipeline was not successful at deriving the astrometry as indicated by the "990 999 0", "990 999 1", "990 999 2", or "990 999 3" values of the ASTROMET header keyword, and the 9999.0 value of the PHOTZP header keyword; the astrometry and the zeropoint were derived manually using the PESSTOASTRO task of the PESSTO pipeline:

Furthermore, for the following 8 reduced images a non-standard used instrument rotation angle required that the "HIERARCH ESO ADA POSANG" header keyword value was modified as 'new posang' = 360 - 'old posang' following which the astrometry and the zeropoint were successfully derived using the PESSTOASTRO task of the PESSTO pipeline:
