Revised MT BOP Software

Description of Output FilesCharles Proffitt, Dec 9, 2008

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

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

.ps3 and .hrps files

Vcrit

“Double”

- Reddened O star- Main Sequence

Limits displayed in .hrps file• For each star with BV estimate, nominal and 1 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 BV– F (red plate) only, plot at BV– N (IR plate) only, plot at BV

• 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 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.
