Version3 Test for Saturation maps

1) northern RTB nights (990523n, 980423n, 971116n, and 000317n)

  a) data: Nothern RTB nights with filtering of j_prg_flg = '000' AND h_prg_flg = '000' AND k_prg_flg= '000' AND k_m < 11
        where new H array data are rom 000317n and the rest is old H array.  rtb run3 (which is finished Apr 29, 2001).
  b) R1 vs Psfmag (or StdApmag) plots
 

	J band	H old array	H new array	K band
R1mag vs. Psfmag	Figure 1.1	Figure 1.5	Figure 1.9	Figure 1.13
R1mag vs. Stdapmag	Figure 1.2	Figure 1.6	Figure 1.10	Figure 1.14
R1mag vs. (R1-Psfmag)	Figure 1.3	Figure 1.7	Figure 1.11	Figure 1.15
R1mag vs. (R1-Stdapmag)	Figure 1.4	Figure 1.8	Figure 1.12	Figure 1.16

Figure captions:  Blue points are all stars and Red points are the sars with Saturation flag.

 c) Remarks from figures:

• Stars are quite well seperated between unsaturationed stars and saturated stars.  There are no faint stars marked with Saturated (no stars saturated fainter than 9.4 mag, for  J band, 9.2mag for H band, and 7.7 mag for K band), and there are no bright stars without Saturation flag. Thus, the saturation flag are overall done correctly.
• The saturation happens  between 8.8-9.4 mag for J band,  8.5-9.1mag for old H array, 8.6-9.2 mag for new H array and 7.7-8.5 mag for K band.

• Why  is theNew H array R1 vs (psfmag) curve  bent? So a lot of data points of R1-Psfmag showsnegative values (i.e. R2-R1 is fainter than R1 values).  South H array shows somewhat similar tendency.=> This is understood due to pixelization problem in new H arrary which was reported by Gene Kopan a week ago.

• There is no bias towards the direction of the scan edge.
• The same plots for H and K also show no bias towards the scan direction.

 f) JHKs color-color diagram: Stars with one band (either J, H, or K) saturation flag  or with two band saturation flags

       Figure 1.19. JHK color-color diagram for one band saturated stars : blue points are all stars, green points are saturated stars in all three bands, and orange points are saturated stars in one band.
       Figure 1.20. JHK color-color diagram for two band saturated stars blue points are all stars, green points are saturated stars in all three bands, and red points are saturated stars in two bands.

•  Stars without saturation flags (green) are well consistent with  the  giant and dwarf tracks in JHKs color-color diagram.
•  One band saturated stars are less scattered than two band saturated stars.

c) Figure captions:  Blue points are point sources and the red points are stars  with Saturation flag.

d) Remarkds from figures:

• Stars are quite well seperated between unsaturationed stars and saturated stars.  There are no faint stars marked with Saturated (no stars saturated fainter than 9.4 mag, for  J band, 9.2mag for H band, and 8.6 mag for K band), and there are no bright stars without Saturation flag. Thus, the saturation flag are overall done correctly.
• The saturation happens  at between 8.8-9.4 mag for J band,  8.7-9.3 mag for H band and 8.0-8.8 mag for K band.
