drawdecam's Introduction

drawDECam

A simple set of matplotlib API to draw DECam shapes using Plot and/or Polygons.

Requirements:

matplotlib (obviously)
numpy
despyastro (needs wcsutil only)

Examples:

import drawDECam as dDECam
import matplotlib.pyplot as plt

# The Center of the Focal Plane
x0 = dDECam.CCDSECTION_X0
y0 = dDECam.CCDSECTION_Y0

plt.figure(1,figsize=(9,9))

# Rotated DECam
# Draw DECam corners using Polygons at center
dDECam.drawDECamCorners_Polygon(x0,y0,rotate=True,color='red',closed=True,fill=False,ec='b',lw=0.5)

# Draw DECam CCDS using Polygons no filling
dDECam.drawDECamCCDs_Polygon(x0,y0,trim=True,rotate=True,label=True,fill=False,ls='-',lw=0.5,color='k')

# Draw DECam CCDS using Polygons fill
dDECam.drawDECamCCDs_Polygon(x0,y0,trim=True,rotate=True,label=True,fill=True,
ls='-', lw=0.5,color='r',alpha=0.1)

# Un-Rotated DECam
# Draw DECam CCDs using Plot function (Unrotated)
drawDECamCCDs_Plot(x0,y0,rotate=False,label=True, color='k',lw=0.5,ls='-')

# Draw DECam Corners using Plot function (Unrotated)
drawDECamCorners_Plot(x0,y0,rotate=False,color='blue',lw=0.5,ls='-')

# DECam Corners on sky -- uses simple 'fake' RA-TAN projection
drawDECamCorners_Sky(ra,dec,pixscale=0.27,label=False,color='k',lw=0.5,ls='-')

# DECam CCDs
drawDECamCCDs_Sky(ra,dec,trim=True,pixscale=0.27,label=False,color='k',ls='-')```
