Description of Output Files

MT BOP Software
• Series of IDL scripts which over-plot
moving object ephemeredes on GSC
images and provides colors and
magnitudes for GSC2 catalog stars.
Description of Main Outputs
• *.cat3 files list stars and colors
– Gives “best” estimate of B-V and also values for 1
s brighter and bluer
– Last column shows filters used to estimate B-V
• *.hrps file plot stars in HR diagram and
overlays various screening limits
• *.ps3 files label stars flagged as of concern
and overplots target track
– *.ps2 files label all stars
– *.ps1 files show fields with tracks but no labels
*.cat3 file gives magnitudes

.ps3 and .hrps files
- Main Sequence
- Reddened O star
“Double”
Vcrit
Limits displayed in .hrps file
• For each star with B-V estimate, nominal and 1s
brighter/bluer values are plotted on HR diagram
(points are connected with a dotted line)
– Star is labeled with same index as cat3, ps2, & ps3 files.
• Use smaller font to mark stars with only one band
– J (blue plate) only, plot at B-V=-0.4
– F (red plate) only, plot at B-V=-0.3
– N (IR plate) only, plot at B-V=-0.2
• Following curves are also plotted
– Limits for unreddened main-sequence stars (solid line)
• taken from IHB where available
– Limits for reddened O5 stars (slanted dashed line)
– “Double” limit from IHB (horizontal dashed line)
– BOT Vcrit limit (dash-dot line)
Labeling in .ps3 file
• *.ps3 file only labels stars of possible concern
– Large font used for stars that would be dangerous
if 1 s brighter and bluer location in HR diagram is
above the limit for reddened O stars
– Small font used for stars where best V estimate
exceeds BOT Vcrit.
– Stars with only one magnitude labeled if brighter
than limit for unreddened O5 star.
